I'm curious about this, as well. In fact, I have 17 days left before I'm placed on unpaid leave for this very reason--despite being 100% remote and the coercion and adverse actions being violations of my state's employment law.
I'm actually in a very similar situation - in fact I'm trying to go on unpaid leave as a preemptive measure. I would happily undertake other mitigation measures, including working remote, biweekly testing, masking etc., and my (extremely supportive) boss has been trying to pull off some alternative arrangement for me, but he's not the one who decides these policies.
