The 2th example of the child command would be to use it to 'remove 2 identities which are in the same resource group with the vm scaleset', the syntax is: az vmss identity remove -g MyResourceGroup -n MyVmss --identities readerId writerId. The 3th example of the child command would be to use it to 'remove system assigned identity and a user identity', the syntax is: az vmss identity remove -g MyResourceGroup -n MyVmss --identities [system] readerId.
