When I shaved and people noticed, I just told them I used to shave that way or that I’ve always preferred it this way, and the only reason I had a beard before was because I was so busy for a while and stopped shaving to save time, so I was just getting back to my normal habits. You can probably find a similar excuse, that you have always preferred it this way and you’re just getting back into it.

I should emphasize: men shave all the time, there is nothing suspicious about shaving your beard, hard stop.
