ASUS TUF Gaming A16 FA608UH - Keyboard backlight not working

Issue description

The keyboard backlight doesn't work, only if I turn it on from Windows and reboot to Linux.

Steps to reproduce

Turn on the backlight from Windows and reboot to Linux, the backlight still works with the brightness and effects, but If I shut down the laptop and turn on and boot directly to Linux, the backlight stops working.

What is the expected correct behavior?

Use the keyboard directly from Linux, without a dual-boot with Windows.
