In case there's some resources available (and I already know the "no" answer)
Gigabyte did a motherboard named: "X870E AORUS ELITE WIFI7".
And as Gigabyte sucs, they are able to create a BIOS update that work with Linux only once in a year (they said they don't care because they only support windows officially).
It could be a good candidate for coreboot replacement (as of today with motherboard revision 1.2, only firmware F6, F8 and F12 are known working with Linux kernel).
