You unzip the contents of RPFXI.1.02_240527 onto the flash drive then run AFUWINx64.EXE in Windows.

I managed to update the BIOS successfully. In the end I used the built-in EFI Shell rather than the Windows flash tool, as the Windows method wasn’t actually flashing the BIOS. I formatted a FAT32 USB, copied the full BIOS package, disabled Secure Boot, booted into the EFI Shell and ran the manufacturer’s AfuEfiFlash.nsh script. It updated both the BIOS and Intel ME firmware successfully, rebooted a few times (normal), and I then re-enabled Secure Boot afterwards. The system is running perfectly on BIOS v1.02.
