In many cases you can just use hole cutouts that are slightly bigger than the knobs, or at least the fixing nuts, if there are any. Lots of audio gear is done that way, but as always, it just depends on the specific case how feasible it is. There are outfits that make stick-on plastic overlays that are quite thin too.

If you or someone else could get the front panel off, you could consider having it covered with hydrographics
