AWS GovCloud Feature Availability Question - Databricks Community

Hi! I'm trying to determine if Mosaic Vector Search (or is it simply called Vector Search) is available on AWS GovCloud?

This shows it is not: https://docs.databricks.com/aws/en/resources/feature-region-support

And it's not mentioned here: https://docs.databricks.com/aws/en/security/privacy/gov-cloud

Can you confirm it's not available?
