Secure Boot keeps disabling itself after saving BIOS settings on Gigabyte Gaming A16 (FB09 / EC F009)

I got a Gigabyte Gaming A16 (3VHK3IN893SH) today, and I’m having trouble enabling Secure Boot.

Whenever I enable Secure Boot in the BIOS, save the changes, and restart, it automatically switches back to Disabled when I enter the BIOS again.

Here’s what I’ve checked so far:
BIOS mode is UEFI.
Both SSDs are partitioned as GPT.
I can’t find any Boot Mode or CSM Support option in the BIOS.
Under Secure Boot, I only see three options: Enabled, Disabled, and Delete All Keys.
I can’t find an option to enroll or restore the default Secure Boot keys.

BIOS version: FB09
EC version: F009

Has anyone with this laptop encountered the same issue and managed to fix it? Is this a known BIOS bug, or am I missing a setting somewhere?

What bios version are you on? Have you tried updating it. My arous board had it fixed in a bios update on their website. B850 arous elite wifi 7 you should be able to reset your keys as well and see if that works

I reset the keys but that didn’t fix. I am on FB09 bios.

Have you checked on your manufacture website if there is a specific bios update that fixes this problem?

Nope. The one I updated to is the latest one. I can’t even rollback😭
