Crazy Apple Pencil

I’d really like it if it were possible to disable the Apple Pencil’s features because when I draw, it goes haywire. In the Apple Pencil settings, the switch from pencil to eraser is turned off because I press it by accident and I can’t draw properly. But in Shotglides, it doesn’t take my settings into account; I’m drawing and it switches on its own, it undoes my strokes, it sometimes erases the whole box – in short, it goes haywire. I’d just like to draw in peace.
