Backlight Keyboard not functioning (Lillipup)

Hello, I’ve been customizing and fixing small issues since getting Xubuntu 24.10 on my Lenovo IdeaPad Flex 5 13" (Lillipup) but can not get the keyboard backlight to turn on. I’m running mrchromebox-2408.1 (09/14/2024) uefi full rom

I’ve downloaded and using ectool however it’s not turning the keyboard light on. It is successfully modifying the backlight percentage however the light itself is not functioning.

I’ve searched for this topic extensively on the forums here but nothing I can find will work, any help anyone can provide would be greatly appreciated!
