iPad hide the "three dots" split screen button

A feature request. I use Vectornator on iPad which has the “three dots” button at the top of the screen to enable split screen. I often hit it by accident while using Vectornator because it is in the same place as some of the toolbar buttons at the top, and the system button takes priority and hijacks that part of the screen which gets annoying.
It looks like there is a way to hide the three dots programmatically from inside the application which would save a lot of frustration. It would be amazing if you could do that either as a setting or a default.

If I try to tap up here:

Then I am hijacked by the system button:

Many thanks,
