How to remove dried wood filler from inside cabinets?

I used this wood filler inside our kitchen cabinets. It’s the first time I used wood filler on something I can’t just go back and sand down over. So I did them all and walked away. When I came back to this project, I realized my mistake. I can’t sand any of this down with messing it up. I have a strong feeling acetone will eat through too much. Is there a way to clean this up without gently chiseling away at it for the every cabinet?

I started this project annoyed I had to do anything to these brand new cabinets at all so forgive my impulsiveness and lack of forethought 😭 I just want to put all of my parents’ stuff back
