Hmmm. I agree with you that fingernail biting didn’t seem to fit the paradigm. However, I did Google “stop biting fingernails”, though, to see if there was any domain specific suggestions. (You may have already done this.)
Two things that maybe seemed promising:
Wear gloves to prevent easy access to hands
Getting a fidget toy to keep your hands otherwise busy
Something else which seems maybe useful is to be mindful/reflective after you’ve noticed that you’ve done it.
Otherwise, I (at least right now) don’t know much about breaking habits without knowing the trigger.
