I’ve got an easy way to do this, I confiscate ‘em ;)

As others have said, this is a management problem.  Untrustworthy parties shouldn’t have physical access to your trunk ports.

That said Layer 2 MAC ACLs should block everything and allow only your switches.

Also do you have lit trunk ports just floating in space?   You shouldn’t...
