In this day and age they should expect you to bring your own device. But they should also not expect you to install any of their software on your device. You simply remote to their machine. They keep it locked down, you get to use your own equipment for all the things you like (music, your personal email, internet, etc).
Or your tasks should be set up so you can do your work using a web browser (in a container - thanks Firefox) and call it a day.
I use Linux for everything and just remote into the works computers to do theirs. I am happy with that. When I went to another country recently I only brought a Steam Deck and was able to do all the work I needed to do.
