'How to enable FIPS endpoint for govcloud AWS gateway (for lambda)?

I have a invoke URL as follows: https://ccvddddXXXXX.execute-api.us-gov-west-1.amazonaws.com/beta I want to implement a FIPS endpoint (so that we are TLS 1.2 compliant). I'm missing the fundamental step here. Is the FIPS endpoint automatically? This doesn't work: https://ccvddddXXXXX.execute-api-fips.us-gov-west-1.amazonaws.com/beta I'm not too familiar with the CLI, so if there is something non-UI can you help provide syntax? thanks!

According to official govcloud docs:

All API Gateway APIs created in GovCloud regions are FIPS-compliant by default.
