Screen off permanent setting

Hi! Just wondering if it would be possible to add a setting that prevents the screen from turning on when using the physical buttons during normal use. For instance, if I have one of my activities running, and a few minutes later I change the volume or I’m cycling through menus…can this occur without the screen turning on automatically? I don’t need to unlock my screen most of the time and/or use the touch functions. Any way to keep the screen off during physical button presses? I know I can touch the screen anytime when needed to wake it up, which works perfectly fine.
