This also has not worked with the previous releases, such as v1.6.0 on NV4x ADL. This should probably be moved to the next releases, not the hotfix ones.

still occurs on MSI ZX90 for both respective v1.1.3 and v0.9.1 releases

Indeed, it is not working on Z790-P v0.9.1, but worked on v0.9.0. We might have some regression either in edk2 payload or coreboot side after rebase...

same for VP4670, the protectli_vault_cml_v1.1.0_vp46xx (coreboot 4.21 rebase) binary
