ThinkPad E14 Gen 3 AMD NM-D481 Password

[rumpumpel1]

I have attempted to remove the BIOS password from an E14 Gen 3 AMD:
System Unit Serial Number PF30PWYB
Machine type model 20YDS03T00
Based on my experience with Intel machines and assuming that the password is stored in the EC, I made a backup of the EC, erased the EC and restored the backup.
Unfortunately the password is still there.
Can someone please tell me the correct way to do this?
Attached is the backup of the EC.
