Ask HN: Prevent monitor turning on during restart?

Hi guys, I'm tinkering trying to do a real-life smartTV/Kiosk for commercials.

I have no problem turning on/off the screen, however given that I do a daily restart, I would like to do it when the screen is off, and keep the monitor of during the restart. The problem is that every time I restart, the monitor turns on automatically.

Is it possible to prevent this behaviour?

Context: I have a script in autoload that decides when turn on/ff based on API call to a backend api. HW is Raspberry.
