What steps will reproduce the problem?
(1) Enroll the device in verified mode
(2)
(3)

What is the expected result?
Success

What happens instead?
Failed to enroll

The enrollment succeeds when the device is in devmode. The reason is there's an error at reading the VPD in verified mode, and the problem is seen in the logs at boot - no need to enroll.

Attached are the logs for both cases: Device is enrolled having devmode enabled, and device is enrolled after verified boot. Also attached the contents of VPD, obtained with:
flashrom -r /tmp/bios.bin -i RO_VPD -i RW_VPD


Interesting places in the logs:
When the device boots in verified mode, the VPD read fails (ui/ui.LATEST):
[WARN] Cannot get eps_base from full BIOS.
[ERROR] getVpdPartitionFromFullBios() failed.loadFile('/tmp/vpd.flashrom.GoHPc1') error.
[WARN] flashromPartialRead() failed, try full read.

[WARN] Cannot get eps_base from full BIOS.
[ERROR] getVpdPartitionFromFullBios() failed.loadFile('/tmp/vpd.flashrom.tr2Brx') error.

When it boots with devmode enabled, VPD is read successfully:
