If you select one of the keys in the keyboard preview on the right, you can add and move keys around to wherever you like :) That should allow you to put keys under your knuckle.

Speaking of palm presses, someone shared a “palmtyl” design with several keys under the palm in the discord (here’s a video: https://youtu.be/D8ev08mnSmg). It’s an interesting way of squeezing in more keys without requiring finger travel.
