[SOLVED] archlinux-x86_64.iso, decrease luminosity?

I wanna install Arch Linux on a tablet PC https://onexplayerstore.com/products/on … 6880063782 that has a OLED display, so (maybe?) subject to screen burn-in, the issue: archlinux-x86_64.iso booted, the luminosity seems at max, so how to decrease it?
According to its keyboard, I tried Fn F6 without success.

echo 49500 >/sys/class/backlight/amdgpu_bl1/brightness

(495000/10=49500) works, thanks.
