Can't get into BIOS or UEFI BIOS. Just black screen every time even after attempted fixes

I just built this computer less than a month ago (first PC build ever) and have been trying to get into the BIOS after installing Windows to set up fan curves and XMP profiles but everything I try hasn't worked. Mobo is an MSI B550 A-Pro.

I'm at a loss on what to do about this, I've tried multiple fixes from the web but none have worked and allowed me to pull up the BIOS so far. I'm also not confident that I didn't fuck something up either in the initial setup or during the attempted fixes. Computer seems to be working fine otherwise (writing this post on it) and boots into Windows perfectly fine if I don't try to interrupt startup. The other thing that is confusing the hell out of me is that at no point during this process has my computer flashed the message telling me what button to spam for BIOS, just jumps straight to Windows lock screen; although my manual says it should be the "Del" key. Really just looking for anything that could help, I have no idea what I'm doing. At this point, I'm wondering if I need to contact MSI to see if they can help me.

Fixes I've attempted thus far, in no particular order:
