That's what I did. I lifted the cap then I lifted the led board. It took me a while but I managed to wiggle it out. Next I unscrewed the torx screw and lifted the entire lighting assembly out. After removing the wires from the connector I was able to pass them through the existing holes without enlarging it. So for me no cutting of the stock knob was required.
I just received the zhp knob yesterday so now I'm going to do the swap. A little unsure on where to drill and how much material to take off the top of the knob. Guess I'll take it slow and follow the directions here.
