This used to be possible with System76 based EC firmware, but the link has been broken due to a lot of changes in the EC firmware. This is a negative result of the break of that. On the other hand, we do no longer depend on other's firmware, which is a plus.

I will discuss with my team the possibility and feasibility to integrate a driver in the Linux kernel to bring this OS controlling functionality back again.
