Hello, can anybody help me to unlock BIOS on Thinkpad T450s, a changed LCD and now the brightness is always 100%. I read memory winbond 25Q128 by programmer. Thanks.

a friend of mine owns a T450 with a JBET73WW UEFI/BIOS. he would like to install a linux on it and somehow the installation stuck at the beginning. he would like to use UEFI only but the installation stops with a blank screen. as far as i understand it's a UEFI issue with a few Lenovo models and several owners facing with this (https://github.com/ventoy/Ventoy/issues/214). is it possible to fix it with modding?
