IBM Db2 z/OS Support for aws_dms_endpoint engine_name

I am migrating data from IBM DB2 z/OS to DynamoDB using AWS Database Migration Services. When setting ‘db2’ as the engine_name for the source endpoint it creates a DB2 LUW endpoint. I don’t see any support for DB2 z/OS. I have seen in other posts that the CLI can differentiate between LUW and z/OS so is there a way we can have a DMS endpoint do this. Will this need to be a feature enchament?

Can someone help with this?
