HP Recommended

I have updated to the latest bios from HP for the HP Z2 G5 Workstation (01.04.20 from around September) and I have used the bios option to 'Reset Secure Boot keys to factory defaults' but the new Microsoft Secure Boot certificates from 2023 have not been put in place yet.  I have also seen the Windows can install the certificates with registry keys if the BIOS supports the new 'SBKPFV3' string.  I am running a Linux OS though so that will not help (RHEL 10 ).

I see mentions of using RHEL's fwupdmgr but it appears that HP does not publish their updates to that.

How can we get the new certificates added manually or is there yet a newer BIOS update that will have the new certificates so that when we reset the secure boot certificates, they will be updated?

Olde certificates are still in place...
