Stop Esc to escape fullscreen

I use neovim editor very much, and one side effect of that is I press esc often by reflex, and I mostly keep apps in fullscreen.

What happens is, when I press esc it exits the fullscreen and it happens frequently.

Required solution

A configureable option to stop esc to exit full screen

Possible blockers

Pressing esc in some UI like search layout exits it. The solution should take that into account and only stop exiting fullscreen.
