Helios 300 (PH315-52) / Ubuntu 20.04 - "Fn + F10" - keyboard backlit / screen brightness

I have installed Ubuntu 20.04 but I think that doesn't matter.
Pressing  "Fn + F10" increases keyboard backlit as it should but in the same time decreases screen brightness, same as "Fn + left arrow"?
I check it and bought key combination returns keycode 224?
"Fn + F9" just decreases keyboard backlit, and not effects brightness and doesn't return key code by "showkey" linux command.

THX for help!

    Nobody had this problem where pressing  "Fn + F10" increases keyboard backlit as it should but in the same time decreases screen brightness, triggering the same action as "Fn + left arrow"?

    THX.

    I don't think its Ubuntu problem, maybe BIOS update can fix it...but i can live with it, for now ;-) THX.

    I have exactly the same problem. Acer Predator Helios 300 running Linux Mint 20.1. Fn+F10 both increase keyboard brightness and decrease screen brightness. Haven't found a fix yet...
