HP prodesk 600G1 DM bios mod for NVME

Hello, I own an HP Prodesk 600 G1 DM mini PC and I want to install a M2 SSD NVME in the dedicate but without success.
I’m trying to Patch Bios HP 600 G1 DM in order to Support NVME SSD PCIe (Booting). BIOS is already patched but I can’t install it.
When using Intel ME system tool, it show error:
Error 280: Failed to disable write protection for the BIOS space!
Can you help me flash modded bios?

I have followed the instructions in
[GUIDE] Grub Fix Intel FPT Error 280 or 368 - BIOS Lock Asus/Other Mod BIOS Flash
My varoffset/varname is 0x97

After boot to grub and change this value successfully to 0x00, i shutdown my pc, and insert jumper to FDO pin in mainboard, then reboot to windows and use this command to flash my modded bios:
fptw -bios -f mod.bin
But the result is: pdr region does not exist
Can you help me?

If everything else went ok, that shouldn’t matter. You should flash it in dos not windows
