How to turn off Ayaneo LED blinking while sleep

Hi! After the bios update, sleep on Ayaneo works fine. However the LED will kept blinking when put it on sleep. Which is quite annoying. Afaik LED driver for Ayaneo devices is this: https://github.com/ShadowBlip/ayaneo-platform It mentioned by modifying suspend_mode file, it can set LED off while sleeping. However when I check the directory, suspend_mode file doesn't exist. I assume the driver in Bazzite is outdated? Or are there some issues with this feature?
