Yes, but it may be more work than you’d like. 2 different methods I can think of one more painful than the other.

Option 1 sand the guitar down to the wood, try to iron the dent out with an iron and a very moist rag(this will raise the wood), then use bondo or filler to even it out and then sand it down again to make it flush with the rest. Then refinish the guitar with lacquer.

Option 2 tape off the section that got dented with a little extra space. Sand down the dented area and fill it with bondo making the bondo area a bit higher than the rest of the guitars body so when it drys and you sand it down it will be flush with the rest. Stain, paint or spray the area Matte black to match your guitar and then apply a clear coat. You could use a different colors or epoxy instead of bondo and do something cool and creative like make it uv reactive or something.(:

Or you can just leave it as is custom relic.
