There was a problem hiding this comment.
This would've been correct if the HMRFPO command sent when entering Firmware Update Mode actually unlocked the descriptor. Instead, it only unlocks the ME region. Once capsule update support was added, this was removed anyway (because HMRFPO wiped capsules from RAM), so the paragraph was outdated in any case.

@mkopec Changed based on our talk. Are you sure that's correct? There is also mention about this in https://docs.dasharo.com/variants/msi_z790/releases/#v091-2024-01-22:
Though maybe that was before capsule support was added?
If that's true, then I guess that this warning is technically correct, but it can easily mislead others to think, that unlocking FD is possible on Dasharo v0.9.1 and newer so I think it's better not to mention it at all.
