Is there any way to unlock the CFG-Lock in my laptop, DELL INSPIRON 3421. My BIOS is O14A13 (link: https://www.dell.com/support/home/en-vn/drivers/driversdetails?driverid=dcgmv&oscode=wt64a&productcode=inspiron-14-3421). I've try using the /writeromfile but when open the file with UEFITool (link: https://github.com/LongSoft/UEFITool/releases) but when open it, it shown some errors and when I find the word "CFG-Lock", it shown no things although I can find the Unicode string "CFG". Thanks a lot for reading my article and helping me.

For the turning off CFG-Lock guide that I'm using is here: https://dortania.github.io/OpenCore-Post-Install/misc/msr-lock.html#what-is-cfg-lock

My laptop does have CFG Lock, though. I've tried running VerifyMSRE2.efi but it has shown that my laptop has registered MSRx0E2 protection so it does have that kind of Lock but I can't find CFG Lock in the BIOS image

Place a check mark next to Custom and change the value to a different value than 64k (I suggest the last one)

Now you should be able to Read and Backup

It now can read my BIOS it now and make a backup (although there is a problem in the parse: "FileHeader: file alignment 10h is greater than parent volume alignment 8h")  but I still can't find CFG Lock and I've tried to extract it into a readable file but didn't work, too.
