Question Motherboard Secure Boot issues

[Sarnecki]

So I'm trying to check out the BF6 beta, but unfortunately, the game will not even let me boot it up without Secure Boot enabled in the BIOS, and I'm a little in over my head here.

https://help.ea.com/en/articles/technical-issues/secure-boot/#check-if-secure-boot-is-enabled

EA redirects me to this website here with instructions on what to do. Unfortunately, my BIOS is listed as Legacy instead of UEFI and my Secure Boot State says "Unsupported." Before I start heading down this reasonably complex string of events trying to reset my board to UEFI and try to figure out how to activate Secure Boot for this silly game, can anyone help me determine if this is even possible to do for my board? For all I know it's not even a possibility and unsupported is literal language. I'm running an MSI Pro B660-A DDR 4(MS-7D59)

I'm also seeing that I'm not allowed to run my OS off of an old MBR partition which I am. I do have a GPT SSD drive I can run Windows on, but this article seems to imply I can covert my older drive into a GPT without having to reinstall Windows or lose all of my stuff?

You could try and convert it to GPT but there are threads around that show that is hit or miss. When I say miss, read data loss. I'd make sure you're on the latest BIOS version for your motherboard, following that, backup all necessary data off of your drive, format the entire drive that you wish to install the OS onto(without other drives connected)and reinstall while having the BIOS set to UEFI(CSM disabled)/fTPM enabled.
Mind you, I'd advise recreating your bootable USB installer for your OS using Windows Media Creation Tools.

That article quite extensively explains,

what you must check and​

what you must do to convert your system to be UEFI compatible and turn on secure boot.​

​

Do all the checks from article.
Provide all the screenshots, they are showing, from your system.

How far did you get?
What causes confusion?

can anyone help me determine if this is even possible to do for my board?

Yes. Your system supports UEFI and secure boot.
This can be done.
