You can always go full there-is-only-Zulu and set the Windows timezone to UTC. (insert head-tapping meme here)

That would fuck over any relative time calculations in calendars (including meetings in google calendar) though wouldn't it?

It shouldn't; I don't use Google Calendar at the moment but Outlook seems to have no problems with people in multiple time zones all seeing the correct time for a meeting.

UTC is the default in many Linux distributions, but I wouldn't say "Linux sets the bios to UTC"; I've only ever seen it be an explicit choice.
