Hi @devsyw,
I believe the documentation is a bit confusing in the terminology it's using to differentiate the Dataverse and Dataverse (Legacy) connectors.
You cannot limit the Dataverse connector at the moment because up until just the last week, the connector only used the current environment you were in.
The Dataverse Legacy (which has a grey icon) connector allows you to select which environment you connect to. That one can be configured to limit the endpoint.
The Dataverse connector just recently introduced an action that allows you to select which environment to connect to, so perhaps they will add endpoint configuration for the connector in the near future, but as of right now you can't.
