I think you can spoof per tab/container. i used an exclusive Firefox Profile for the bad/contaminated (read: not privacy respecting) browsing - in there i’d ocasionally switch the UserAgent to make Teams calls.
there’s no way i’d work on a machine with M$ spyware installed and always running
You can make it work by changing your UserAgent string (there’s plugins for that) to some older chrome version to make things work.
Or you opt for an operating system that lers you roll-back whole generations for when such a thing happens (GNU Guix for the win!)
