I recently set up my new PC with an A520 MATX motherboard and enabled Secure Boot. Unfortunately, now my screen is completely black, and I can't access BIOS at all. I've followed all the troubleshooting tips I could find, such as removing the CMOS battery and trying to reset the motherboard. I even unplugged my new GPU and connected my monitor to my old GPU, but nothing has worked so far. I've scoured the internet for solutions, but I'm still stuck. Has anyone experienced this issue recently and managed to find a fix? Any help would be appreciated! Thanks!

If you're using DisplayPort, switch to HDMI. A lot of GPUs seem to have issues with Secure Boot when connected via DP, but HDMI usually works without a hitch.
Sounds like it might be a BIOS recovery situation. Look into your motherboard’s BIOS recovery method; that usually involves putting the BIOS files on a USB drive and using a specific USB port to restore it. Also, it's possible you enabled Secure Boot with a GPU that isn't compatible, so trying a newer one could help. If nothing works, you might end up needing a new motherboard.
What CPU do you have? Your BIOS might not support it yet. You can check that on pcpp. It could also be a RAM issue, lack of power to components, or a damaged PCIe slot.
It was all working fine before I enabled Secure Boot, so I’m thinking it’s definitely related to that.
I’ve got both HDMI and DP monitors, but I’ve tried both, and it's still not working.
