Teams Meeting Room & PIN

We are about to create more meeting rooms and I got asked if we can't use an MTR system instead of Clickshare that we use in current rooms.

My issue is that a lot of meetings doesn't use the room, today that is not an issue but with an MTR it might be an issue if the meeting ends up WFH only and then some random user walks in the room and can join the meeting as the room.

Is it possible to always demand a PIN when you are joining a meeting from an MTR and not for everyone in the meeting?
