With everything else equal, a larger wheel has a larger contact patch and smaller angle of attack. So the bumps would be less pronounced. Longer wheelbase also would help. Then comes frame geometry and material. Rigid bike designers can use a lot of tricks to improve the situation.
suspended bike designers can optimize the frame and wheels for other things.
Look at the
Jones bike that is thoroughly designed to be a rigid bike.
