Coreboot has a payload for that in payloads/nvramcui

You could compile it and try to launch it from GRUB or SeaBIOS.

Else nvramtool under GNU/Linux also permits you to change such options.
You could also do a minimal rootfs with nvramtool, and optionally write
a GUI to do that.

This probably means that your battery doesn't charge anymore.

I don't think it's specific to libreboot, however If the
battery doesn't charge anymore with libreboot, it probably won't either
with the stock BIOS.

The tp-smapi external linux module has more control over the battery
charging, but while the module is free software, it depends on the
non-free BIOS to work.

More precisely, it depends on its SMM code. I wonder if such
functionalities could be achieved without the non-free BIOS.

I vaguely remember that it also had some kind of i2c access to
the battery. Maybe that could be achieved with free software, giving us
way more control over the battery.

At this point standard Linux (battery) drivers or Userspace(i2c-tools)
tool would work with it.
