Yes! Turn the L screw all the way clockwise, then turn the H screw all the way counterclockwise. This will cause the little tabs to face each other. With a small pick tool , carefully pry up the little metal frame that surrounds the caps. It will take some effort to get it out of there without breaking. ThAt done, the caps will come right out and you can trim off the little tabs on the side with a sharp knife. Then put the caps back on the screws and make sure you have full motion with each. Press the little metal frame back in and your done!
Or, you could just swap it for my CS-450 which already has this modification...:tongue2:
