Acer Secure Boot 2023 Certs

Has anybody successfully updated their Secure Boot Certs on these Computers:-

Acer Predator Orion 5000 PO5-600s
Bios VR01-A4 (Desktop)

Acer Predator Helios 300 PH317-56
Bios V1.12 (Laptop)

Both computers display this in the Windows Security/Device Security/secure boot section:-

Secure Boot is on, but your device does not support the automated Secure Boot certificate update due to hardware or firmware limitations.
Contact your device manufacturer for assistance.

Not sure if the only way is via the OEM issuing Bios and or Firmware updates or some sort of work around.

Any help or information would be greatly appreciated.
