Disable test mode navigation without needing to be in prod

Is there a way for us to use the test mode form but not show the test mode navigation?

The test mode menu nav is great when we legit are testing or building a new experience. however, we have a staging environment that we use day to day internally and this nav shows all the time which isn’t ideal. This is especially problematic on mobile web where that nav gets in the way a lot.

Is there a flag to pass or a way we can hide this while still using our test key?
