Based on the article you have posted, my understanding is that c6a.4xlarge is not ENA compatible and m5.4xlarge is.

Yes, you are correct. There are differences esp with the network adapator.
Please see https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/resize-limitations.html for Compatibility

For Windows installation instructions, refer to Enable enhanced networking with the Elastic Network Adapter (ENA) on Windows instances
