I poke around in my Pinephone configs to somehow disable notification LEDs and /sys/class/leds seems very promising but for some reason the max_brightness file which seems like the easiest solution to me is read only. Dose anyone here know if there a safe way to set that to 0 or will I break stuff if I work around the limitation and will it even help? 

 Found a decent solution, there is also a "repeat" file in there, it won't allow 0 as a value but if you set it from -1 to 1 the LED will only blink a aingle time! 

 @33109f92 what does 'ls -l /sys/class/leds/max_brightness'' give? I think of 'sudo echo "0" > /sys/class/leds/max_brightness' but IDK.
