I accidentally disabled CSM support and enabled Secure Boot on my A520M K V2 motherboard while using an RX 580 graphics card. Now, my monitor shows only a black screen. I've tried everything suggested online, including removing the CMOS battery, but nothing seems to work. How can I get back into the BIOS?

It sounds like you might need to flash your BIOS to reset everything to default settings. You'll need access to another computer to create a bootable USB drive with the BIOS file. Check the manufacturer's website for guidance on that.
Have you tried resetting the BIOS by using the pins on the motherboard? Just removing the CMOS battery might not be enough. You can usually do this by using a metal object to connect the two reset pins for about 5-10 seconds. That should help reset the BIOS settings. Just make sure to unplug the PC from the wall before doing this!
