If it works via JTAG, that would be great. If I understand correctly, some have already tried, but it didn't work.
If it doesn't work, then there are only two options (in my opinion):
1) easier - replace the EC chip
2) more difficult - edit the EC firmware so that it clears the memory block with the password. However, I don't know if the firmware is signed. It's possible that the modified firmware won't even start....

You can extract ME from update or download it from winraid.level1techs.com.
I assume that after changing the ME region the password will remain....Leave a comment:

I can't say for 100%, but it seems that in this laptop the password is stored inside the MEC1723N and at the moment the only option to reset the password is to replace this chip.

Hello!
If I understood correctly, there is an update for the ME region on the manufacturer's portal.
In the "Motherboard Devices" section, there is a file "Intel Management Engine Firmware for Windows 11", version 16.1.35.2557.
After unpacking, there are two files with the .cap extension.
Maybe someone can tell us how to extract the region from such a file?)
ps The unpacked region with this version is on the winraid.level1techs.com portalLeave a comment:

Thank you.
p.s. For history. The dump from the first message is correct, it can also be used to restore your device.Leave a comment:

ps I didn't find this serial number in the dump, and there are no matches on the Lenovo website either.
If I understood correctly, the serial number is stored in the ECLeave a comment:
