Asus laptop all keyboard fn shortcuts work except for brightness

I have ASUS TUF Gaming A16 FA617NSR and I have kde plasma and g14 custom kernel installed, fn f7 (brightness increase) and fn f8 (brightness decrease) doesn't work but other fn keys do. I already tried adding "pcie_aspm=force" and "acpi_osi=" kernel modules but both did nothing and actually adding  "acpi_osi=" made grub stuck at initializing arch linux part.

        Current brightness: 179 (70%)
        Max brightness: 255

        Current brightness: 0 (0%)
        Max brightness: 1

        Current brightness: 0 (0%)
        Max brightness: 255

brightnessctl works but I couldn't manage to make a shortcut for f7 and f8 keys.
