Disable approving reviews of external contributors

I wonder if it is possible do disable the “approve” button for external GitHub reviews. Many people click it without articulating themselves. It is one thing for a core dev (who you know) to do that, but coming from a third party it does not help. GitHub of course encourages this because a review shows up as an “activity”.
