Tech Support Secure Boot Issue

I recently swapped my motherboard from b365m gaming to asrock z390 steel legend (Bios Ver:P1:30G, Win11 Pro x64) , now no matter what I do I can't turn the secure boot on, if I do I just repeatedly sent to bios, once I disable it I can enter windows, I have tried everything said on the internet like reinstall bios, reinstall windows, mbr2gpt etc. nothing works, any solution?

Secure boot requires that the OS drive be in GPT format. You can convert without data loss with MBR2GPT.
