You can still not comply and see if they end up terminating you. If they value you as an employee enough they may begrudgingly be willing to look the other way.

I've had companies try several times to bring people back to the office, just to have most people not show up anyway (or show up only every once in a while), and so far I haven't seen terminations enforced. That may eventually change, but at least so far I haven't seen that happen. YMMV though.
