Function bar backlight - how to turn off? (xps 13 plus)

Hello,

how can i disable the backlight from the function bar?

There are multiple request on reddit from people who want the same.

It ist very annoying in the dark. Like when you want to read something or watch a movie. There is no option in the bios to turn off the function bar backlight. Will this funtion be added in the future?

I think it would be a great thing on a 3k € notebook, if you are able to control the backlight.

Thanks
