As part of parameters, is it possible to configure one parameter to accept an existing aws kms key in the same account. It would be super useful, if its possible to list them as part of dropdown. I know the supported parameters types doesn't take in aws:kms:key . Just want to explore if there any other ways.

You can only have the drop-down functionality for AWS-specific parameter types.

Unfortunately, as mentioned in the documentation, these types are limited to a few and do not include KMS keys.
