Motherboard: Z490-A Pro
CPU: Intel i7-10700KF
GPU: NVIDIA GeForce RTX 3080
Windows Version: Windows 10
I'm attempting to turn on secure boot to play Battlefield 6, following all their instructions. However, after rebooting from BIOS with secure boot enabled, my PC's screen flickers briefly before displaying a blackish screen. I verified I'm using UEFI, TPM 2.0 is active, and the hard drive is set to GPT mode instead of MBR. I also changed the secure boot keys from custom to standard and applied factory settings. I'm unsure what else I should try at this stage.

I've attempted to refresh the BIOS using the flash tool, but each time I try, the file remains hidden and only shows a folder named "system informations update."

It might be helpful to explain the process used to create the USB drive containing the BIOS file.

I didn’t find a BIOS version that matches your setup. It’s possible MSI removed it because of instability concerns and replaced it with a more reliable option. Please note the BIOS details you provided are specific to MSI motherboards. I can verify this is indeed an MSI model.

USB Format
BIOS Version
I included an image of the BIOS version. I utilized Rufus to completely erase the flash drive and its partitions, followed by using a Windows utility to format it.

I checked that I am on UEFI
Your screenshot tells me you're on a hybrid UEFI mode, with CSM enabled.
Give this guide a whirl;

Here's a simplified guide of the above;

Which also leads me to ask, is your system a prebuilt?
Please be wary that there's a risk that flashing your BIOS can result in a bricked board if you have any hiccups along the way, like a power failure mod BIOS update process.

I believe it was a prebuilt one I obtained from the FB marketplace. Usually I avoid prebuilds, but now I'm regretting it. How do I verify if it's a hybrid version? In my BIOS I had an option to choose between UEFI and it highlighted that one. Also, when checking system information it only shows UEFI.
