did you manage to update? i have the same card/version and it's failing for me too

Sadly no, for whatever reason the NVM / Flash chip is write protected according to the eeupdate64e tool :(

You can check yourself by using the command

eeupdatew64e.exe /NIC=1 /IDFLASH

tl;dr: Have you tried disabling secure boot?

I was seeing "Error:      Flash update failed." when attempting to update from Win 11 (using nvmupdatew64e.exe 1.41.3.1 from Intel® Ethernet Adapter Complete Driver Pack 31.1. Then I tried with Debian 13. The recommendation to set iomem=relaxed only works if I disable secure boot, otherwise that flag is ignored. After setting the kernel cmdline and disabling secure boot, I was able to successfully flash my I226-V from 2.17 to 2.32. This is the Ethernet controller that came with my MSI MAG Z790 Tomahawk motherboard.
