How do I turn off the Apple Pencil screenshot gesture (swiping up from bottom corners)?

I need a way to turn off the screenshot Apple Pencil gesture (swipe up from bottom corner).

I use the iPad for digital painting and this unwanted gesture is extremely irritating. If I need to paint anywhere near one of the corners, Apple's screenshot interface pops up. How do I get rid of this?

Working on an iPad Pro, but I would assume this happens on all iPads.
