You could use a slotting strategy and tabs (at the bottom) to retain the piece if you wanted to save the material. Then cut the tabs out by hand. Optionally do another finish pass after manual removal if the wall surface matters. But I’d probably just use an adaptive strategy to turn it into chips. Easier and probably faster. As long as you can clear the chips without standing there with an air gun or vacuum.
