I recently tried enabling Secure Boot in my BIOS to play Battlefield 6, but it seems to have caused some serious issues with my PC. Here are my system specs: I'm using a Gigabyte GA-Q170M-MK motherboard, an Intel i7-6700 CPU, and a GTX 3050 GPU, running Windows 10. After I enabled Secure Boot, I got an error saying that CSM (Compatibility Support Module) was loaded, so I attempted to disable it. Unfortunately, saving and exiting the BIOS didn't help, and now my PC doesn't even POST, making it impossible for me to modify any BIOS settings or get into Safe Mode.
Before the problem arose, I ensured my BIOS was set to UEFI and confirmed that TMP 2.0 was active with GPT on Disk 0. I was prompted that there were no valid keys for Secure Boot, but when I followed some online advice to reset factory keys and set storage to UEFI, my PC just started powering off and on every few seconds, without reaching POST or displaying anything on the screen.
Currently, my PC cycles power every 3-5 seconds, the HDMI display flickers with no text appearing, and none of my troubleshooting efforts—including removing the CMOS battery—seem to have worked. I'm looking for advice on how to regain BIOS functionality and if my motherboard supports QFLASH for recovery. Any help would be much appreciated!

First off, try resetting the CMOS with the jumpers on your motherboard. Power it on while shorting the CMOS reset pins for about 30 seconds, then remove the short and press reset. Check your motherboard manual for the exact location of these pins, usually listed under 'CLR_CMOС.' Let me know if this helps or what you see after doing it!
I did short the CMOS jumper for 30 seconds. It actually kept the PC running for about 20 seconds longer, but then it went back to rebooting every 3-5 seconds. The HDMI still flickers, and I can't see anything during POST. I'm worried my motherboard might be bricked!
