[FP5] Smart Charging not available - Advanced Charging Controller (ACC, root needed)

Somehow a cross post of:

Is Smart Charging missing for other devices as well in iodeOS v4.9?

Anyone running iodéOS rooted and ever used acc?
(see some details in the FP Forums thread, but I guess the acc dev will know that it is Kernel related, so for other devices it might work)
