          had limits increased by AWS support.
  
          This method calls :py:meth:`._AwsService.set_limit_override`
          on the corresponding _AwsService instance.
  
          Explicitly set limit overrides using this method will take
          precedence over default limits. They will also take precedence over
          limit information obtained via Trusted Advisor, unless ``override_ta``
          is set to ``False``.

          :type limit_name: str
