Windows Secure Boot certificate issue

[Oloyede]

I have an HP EliteBook 840 G5 that's affected by the Microsoft Secure Boot issue - Device security Devices in this group are affected by a known issue. To reduce risk, Secure Boot certificate updates are temporarily paused while Microsoft and partners work toward a supported resolution. Contact your device manufacturer for assistance.

According to this article, my model is not on the list of PCs to receive an update that addresses that.

Anyone have an idea what I'm supposed to do next? I have tried downloaded the BIOS update from the HP Support website, but the last BIOS update for my PC model is Q78 Ver. 01.31.00 - 03/10/2025.

What if I downloaded the BIOS update for 840 G6, since it's on the list in the above article? What are the potential consequences?

Any assistance will be appreciated.
