imdsSupport

Set to v2.0 to indicate that IMDSv2 is specified in the AMI. Instances launched from this AMI will have HttpTokens automatically set to required so that, by default, the instance requires that IMDSv2 is used when requesting instance metadata. In addition, HttpPutResponseHopLimit is set to 2. For more information, see Configure the AMI in the Amazon EC2 User Guide.

If you set the value to v2.0, make sure that your AMI software can support IMDSv2.
