For enemies, right now there isn't. I recall it being brought up before as something someone else wanted to do, but wasn't able to. I assume you can do it for a male player character, because there are all sorts of customization options, but again I've only done female characters myself.Is there a way to remove facial hair from male characters?
One of the suggestions for DLC that got suggested by some people in the discord (I was one of those who made the suggestion) was the ability to fully customize enemy units like you can customize yourself. It was a little while ago, and from what I remember we didn't get confirmation one way or another that it would be included in the future, but there is hope, because Zed does plan to come back to add more content to the game after making some progress and demos of his next game Kinky Fight Club 2.
This was all a long winded way of saying, you're stuck with the facial hair for now. If you're lucky, in the future you can do something about it.
