How to enable Secure Boot on AMD based Gigabyte motherboards?

I've checked the BIOS settings and I see the option to enable Secure Boot, but every time I try to enable it, I get an error message saying that Secure Boot is not supported by my CPU or motherboard. I've tried updating my BIOS to the latest version, but the issue persists. I've also checked online documentation and tutorials for similar motherboards, but none of them seem to mention this specific issue. I'm not sure what I'm doing wrong or what I need to do to get Secure Boot working. Can anyone help me troubleshoot this or provide a solution?
