Thinkpad L14 G2 AMD (NM-D391) Power On / Supervisor password

[kitor]

Hey,
I just revived this motherboard (fixed no POST, thanks to a BIOS from this thread)

Now there's a supervisor password required on power on. It is stored likely in EC, which is Nuvoton NPCE68BPA0DX (sometimes misspelled as NPCE688).

I've seen some success on reading this chip in thread for Intel version of this laptop here.

I have access to RT809H programmer. Is there any chance of programming this EC with it? If not I guess I need to find someone with vertyanov?

Or maybe there's a way to bypass just power-on requirement by modifying main BIOS chip (Winbond 74M25JWEIQ, 32MB)?
