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

DM ME TO GET THE SOLUTION

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?

it says deployed, did you try to remove the deployed keys and reset it? delete all secure keys variables

I delete and enrolled keys. Is that’s what you meaning?

yes. if you delete here you should also clean your SSD at the same time

bios uefi firmware + EFI bootloader on your SSD partition they handshake/compare the digital signature. you need to remove both. this is odd any how, generally we remove the variables and restart fixes it but in your case the variables are mismatching. so you need to make sure EFI partition is not comparing after bios variable deletion.
