Many Orthodox Jewish doctors (= wear yarmulkes at work) do not have beards. Trying to present different customs within the context of Orthodox Judaism to a goy never worked for me. Maybe it will work for you. Even if you get away with it, they will be looking for reasons to get rid of you. You will be considered one of the Orthodox Jews who don’t follow Corona virus regulations.
Instead, I would recommend that you buy a cheap electric razor. You won’t have a beard, but you will look unshaven. (They are cheap because they don’t work that well.) The N95 will fit just fine, so the cheap electric razor is the best compromise. When you go to the Rav, ask him which electric razor he recommends.
