I want to try reduce the brightness of the keyboard backlight on my Lenovo Yoga 2 13" - it only has one setting.

It's running an InsydeH2O v3.7 BIOS.

I noticed it fades in and out when turning it on and off so I figured it's probably PWM controlled. I found a schematic online and it shows it's connected to the BIOS via a PWM GPIO.

So now I'm looking for a way to adjust it. Is it possible? And how would I go about it? 

Apologies if this is in the wrong place.
