Old Zoom Room controller reconnecting to Zoom

[SJL3]

One of our Zoom Room controllers was stolen, so we replaced it (both Mac minis). We removed the old controller from the Zoom Room devices page, and confirmed the new one shows up instead.

However, after some time, the controller disconnects from our account saying "this room is no longer available it is now in use in another location", and the old controller reappears under the Devices page for the Zoom Room.

We're assuming the stolen one is being turned on and automatically reconnecting to Zoom Rooms and kicking off our current one. Is there a way to permanently prevent this old controller from pairing with our account?
