Hi all, trying to unlock hidden BIOS settings on an HP M01-F0024 desktop (Erica2 motherboard, SSID 8643).
BIOS version: F.41 (09/17/2021) CPU: AMD Ryzen 5 3400G (AM4) Chipset: AMD B550A
What I need:

Above 4G Decoding offset

I have setup_var working from Linux and can write EFI variables directly — I just need the VarStore offsets from the IFR. Attaching BIOS file (086F3F41.EXE from SP141980).
Thanks
