My personal opinion – if you are even minimally contributing to healing people, esp from the pandemic, then you should focus solely on the mitzva at hand and do what makes you do that job better, including being on good term with your boss. If you are not contributing, then just change the job. Why hang out in N95 if you could work from home.
Quick check seems to show that Sikh see beards as more important, in some cases agreeing to martyrdom not to shave. Anyway, you may also want to ask your wife or shidduch consultant. At least, keep a picture of yourself with a beard to prove your social status.
