RX 560 no UEFI?

[TakeYouHigher]

I tried to disable the CSM to enable Secure Boot but when I enter the Bios the CSM is automatically enabled (I have a B450 Aorus M) so basically, when I disable the CMS it enable by itself. Is my gpu doesnt support UEFI? GPU-Z says it supported but no idea why it's not working. My Drive is formatted with GPT. Obs: I'm using a custom vbios attached in this thread but the original one doesnt work either. My GPU is a Biostar RX 560D (VA5605RF41). Please, can someone help me why my CSM keeps enable by itself?

If UEFI wasn't supported you wouldn't be able to see or enter the BIOS and have a blank screen until Windows was loaded, what is your issue? you can enter the bios, boot into Windows etc?

When I disable CSM to enable Secure Boot the CSM automatically set to Enable after save bios settings. So basically I can't disable CSM

Edit: I forgot to say but when I disable CSM with the original vbios it have a blank screen until Windows.

Do you need to use secure boot? you could use the AMD GOP patcher, though the old adage goes if it isn't broken don't fix it, I've not done this in a while so I can't instruct you on how to do it but there are lots of guides on the web, and @eidairaman1 might be able to chime in with his expertise as the resident AMD BIOS flashing guru, there may well be a UEFI enabled BIOS for your particular GPU

Yes, I need it cuz a few games like Valorant says the Secure Boot is necessary to run on Win11.

Then you need to flash a UEFI BIOS to the card or use the GOP patch, can you post a screenshot of GPU-Z and the white stickers on the back of the GPU?

I already sent a gpu-z screenshot, you mean a new one with the original vbios information? Here's the white sticker on the back

Replace the cmos battery, Update your motherboard bios, if it continues Contact Gigabyte or replace the motherboard.

Do you think the motherboard is the problem? My bios is updated
This issue happened with my old motherboard too (b450m DS3H v2)

Motherboard should be UEFI compatible for sure, that's a Ryzen b450 chipset? some older RX 500/400 GPU's didn't have full UEFI support, they're rare but did exist

I have a reference Polaris card and it works fine with my Biostar X470GTQ (American Megatrends) UEFI (so same generation as B450). I have Secure Boot disabled and run Linux though.

I flashed with the 230695 but after disable CSM it keeps a blank screen until the windows start like my original one.
The patcher is not finding the vbios with the 232624 or the 233430
