Broken BIOS setting mapping/efivars on Bazzite 41

[Emiliopg91]

Describe the bug

after upgrading to stable-41.20241029 of image bazzite azzite-asus-nvidia-open, efivars stopped working so there's no way to control anything using rog-control-center

At the begining I thouth that it may be due to a rog-control-center bug, however i tried to run following command:

fwupdmgr get-bios-settings --json. The expected output was:

"BiosSettingReadOnly" : "false",
"BiosSettingType" : 1,
"BiosSettingPossibleValues" : [

"1"
]
}
]
}

but the actual output is
{
"BiosSettings" : [ ]
}

So the problem is for sure the kernel integration with bios/firmware. It works perfectly on stable-40.20241020, so I reverted inmediatly

Please check it and do a regression for asus image

What did you expect to happen?

Mapping bios settings to it's corresponding efivar to allow rog-control-center or any other sofware to edit bios settings and adjust power limits to computer APUs

Please use ``` to quote code blocks

/sys/class/firmware-attributes/asus-bioscfg is something that is set by the out-of-tree patch series asus-linux is preparing to submit upstream. We do not carry that patch series on the new kernel.

This makes this a feature request. I will try to weed through the random series he spams online and merge part of them in.
