The keyboard backlight does not work

I have an Asus chromebook cm3401 with windows 11, also before that I had an Acer chromebook 514, and on both of them after installing windows, the keyboard backlight does not work, they are both on ryzen processors, so my question is - on chromebooks with ryzen processors, the keyboard backlight does not work at all? Is there any way to fix it? On Chrome os and Linux everything works.
