I would love to see Romulans get the option to apply facial hair. That is really all my character needs! Lol. I know it's not canon in the show, but the could be for many reasons. We know Vulcans can grow it due to Spock in "Mirror, Mirror" but none in the Prime Universe have any. (I think Sarek does in Disc, from what I have seen in trailers but I haven't seen it.) Idk if a Dev will see this and let me know if I can plan on it coming or not.
