Where a customer has decided not to use position management at all, is there any way to hide all position related fields and quick actions?

There are a lot of screens with position related fields, basically any that create or update assignments, and several position related quick actions.

I'd like to think there would be a master switch that would turn position management off and automatically hide everything position related, but I'm not aware of one. If that's the case, then does it come down to personalising every single field, page and quick action that relates to positions?
