SER5 Secureboot on Linux and BIOS update

Beelicious

Emailed Beelink support, but not sure how fast I might get a response. Posting here as well to potentially get more help, or get it quicker:



I have 3 SER5 devices, all model:
SER5 PRO-E-16512EJ0W64PRO-DP/XB
They are Ryzen 7 5700U devices, so I assume
https://dr.bee-link.cn/?dir=uploads%2FSER%2FBIOS%2FSER5700
is the proper directory for downloading a BIOS update?

One is running BIOS version SER5H507
Two are running BIOS version SER5H508

I see a 509 version is available. Can 507 jump directly to 509?
Anything else I need to be aware of?

Also, I'm getting rid of Windows and setting these up with Linux. Once in linux, security settings tell me Secure Boot is not functioning properly due to it being off or keys being invalid. Even after turning it on within settings and loading factory default keys, the error within Linux persists. Seems the Platform Key within bios gets set to "Do not trust- test AMI' and is insufficient...

Will a BIOS update fix the PK issue? Do I really have to add the key manually, on my own?
