Pc help

I made some BIOS changes last night (Secure boot to play valorant), now PC won't boot at all - EZ Debug LED goes from CPU to DRAM then finally stays on VGA. I'm getting no display whatsoever so can't get into BIOS to do anything. Have taken out battery and shorted JBAT1. No joy. Also tried with different monitor, cables, and graphics card. Any thoughts? If I pop a USB in with a BIOS update + QFLASH+ It starts blinking then turns into a solid colour while also having the CPU debug light on. Parts are: Gigabyte Z790 UD AC MOBO, i7-13700kf ROG STRIX 3090 Is the MOBO just bricked? Ik this is really technical but was just wondering if anyone else encountered something similar when trying to play valorant

Might be worth contacting gigabyte about this, especially if you still have warranty. If you’re unlucky it could be something like the BIOS chip being scuffed and I doubt you want to sit and solder a new one in especially if you have warranty.
