@arthursun0104 - You’re welcome! Before you follow next guide, disable secure boot, remove any BIOS password, and disable TPM/Encryption if enabled.
Then, follow this guide - Go to section 2.2 and make bootable USB with RU program, then read 2.3-2.5

You will change the following in “PchSetup” not “Setup” as the guide mentions >> Change from 01 to 00
BIOS Lock, VarStoreInfo (VarOffset/VarName): 0x17
And this one, just check to be sure it’s 00 already, it should already be 00
Flash Protection Range Registers (FPRR), VarStoreInfo (VarOffset/VarName): 0x6DD
Once done, reboot to windows and do step #1-2 FPT again with new name, such as biosregnew.bin. Once you pass step #2, send me the biosregnew.bin file
