disable the palm of your hand when drawing in Photoshop

Hello,

I have a Wacom graphics tablet and Photoshop.
I would like to draw in Photoshop, using the touch controls to zoom in and out on the drawing board. It works, but it is very annoying that, while drawing, it also takes the touch of the palm of your hand, and this creates big problems when drawing.
Is it possible to disable the touch of the hand during the drawing phase and only have that of the pen? But keeping finger shortcuts to zoom in and out.

Thanks
