There is a command group 'az_iot_hub_module twin'. This group of commands could 'manage iot device module twin configuration'. The group of commands has global parameter '--debug' which means 'Increase logging verbosity to show all debug logs.'. The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'. The group of commands has global parameter '--only-show-errors' which means 'Only show errors, suppressing warnings.'. The group of commands has global parameter '--output -o' which means 'Output format.'. The group of commands has global parameter '--query' which means 'JMESPath query string. See <a href="http://jmespath.org/">http://jmespath.org/</a> for more information and examples.'. The group of commands has global parameter '--subscription' which means 'Name or ID of subscription. You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_iot_hub_module twin_update'.The syntax is: az iot hub module-twin update --device-id
                              --module-id
                              [--add]
                              [--auth-type {key, login}]
                              [--desired]
                              [--etag]
                              [--force-string]
                              [--hub-name]
                              [--login]
                              [--remove]
                              [--resource-group]
                              [--set]
                              [--tags]. The 1th example of the child command would be to use it to 'patch module twin desired properties', the syntax is: az iot hub module-twin update -n {iothub_name} -d {device_id} -m {module_id} --desired '{"conditions":{"temperature":{"warning":70, "critical":100}}}'. The 2th example of the child command would be to use it to 'patch module twin tags', the syntax is: az iot hub module-twin update -n {iothub_name} -d {device_id} -m {module_id} --tags '{"country": "USA"}'. The 3th example of the child command would be to use it to 'patch module twin tags with json file content', the syntax is: az iot hub module-twin update -n {iothub_name} -d {device_id} -m {module_id} --tags /path/to/file. The 4th example of the child command would be to use it to 'patch removal of  critical  desired property from parent  temperature', the syntax is: az iot hub module-twin update -n {iothub_name} -d {device_id} -m {module_id} --desired '{"condition":{"temperature":{"critical": null}}}'. The parameter '--device-id -d' is required. It is used to target device id.. The parameter '--module-id -m' is required. It is used to target module id.. The parameter '--add' is optional. add an object to a list of objects by specifying a path and key value pairs.  example: `--add property.listproperty <key=value, string or json string>`.. The parameter '--auth-type' is optional. indicates whether the operation should auto-derive a policy key or use the current azure ad session. if the authentication type is login and the resource hostname is provided, resource lookup will be skipped unless needed.you can configure the default using `az configure --defaults iothub-data-auth-type=<auth-type-value>`.. The parameter '--desired' is optional. twin desired properties.. The parameter '--etag -e' is optional. etag or entity tag corresponding to the last state of the resource. if no etag is provided the value '*' is used.. The parameter '--force-string' is optional. when using 'set' or 'add', preserve string literals instead of attempting to convert to json.. The parameter '--hub-name -n' is optional. iot hub name or hostname. required if --login is not provided.. The parameter '--login -l' is optional. this command supports an entity connection string with rights to perform action. use to avoid session login via "az login". if both an entity connection string and name are provided the connection string takes priority. required if --hub-name is not provided.. The parameter '--remove' is optional. remove a property or an element from a list.  example: `--remove property.list <indextoremove>` or `--remove propertytoremove`.. The parameter '--resource-group -g' is optional. name of resource group. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--set' is optional. update an object by specifying a property path and value to set.  example: `--set property1.property2=<value>`.. The parameter '--tags' is optional. twin tags..
