What Jesse and Paul said – but put a piece of cardboard that is the thickness of the saw blade between the drawers as a spacer. Do not run the cardboard all the way to the veneer – leave a 1/4” gap. Doing this gives you the space for the saw blade. Cut down toward the cardboard. Practice this on a mockup a few times first.

Do not disconnect the boxes (remove the cardboard) until the cut is complete or you can splinter the veneer.
