so after a few trial and error i figure out how to remove absolute in this sh*t.
first thing you need to do is unlock the bios password.
in this block address from 00037000 to 00037930 use any hex editor fill with hex (ff)
then use this patched main it will auto recover DMI and unlock the absolute lock. it also works in no display/ late display no need Rebuild.
at first boot it will promt final step of bios update. be patient
no need to reset security defaults. it will promt controller error just enter and it will also promt identity mismatch but its okay just click enter and viola its done.

or you can use BCU (after unlock bios) to read config and change Absolute * from Lock to *Unlock, save file and write new config file. Also you can permanently disable Absolute in config file.

Hello my dear friend! It seems that I accidentally removed and lost one diode near the chip, now the laptop does not turn on. I can't say the result of the firmware.

Hello! The service installed the resistor I needed, which I accidentally removed. But unfortunately the laptop does not turn on with the original and unlocked BIOS. The diode on the Caps Lock button lights, and the diode on the charging port blinks white, power button doesn't turn on. I think the problem is with the BIOS, what can you advise?
Here are the original bios:
