No display after BIOS update

Hello.

MB: ASRock B550 Phantom Gaming-ITX/AX
CPU: Ryzen 7 3700X
GPU: Nvidia geforce 3060ti
Here is full pc specs: https://pcpartpicker.com/list/X3nvmC

So i had wifi card issues and i tried everything except bios update i decided to update my bios, i had v 2.20 and updated it to 3.47, which in face at the end showed successful. After the update it restarted and that's it, kept running, no display or anything. Keyboard lights etc all light up just no display.

After some digging as i understand the MB doesnt recognize gpu and since ryzen 7 doesnt have any GUI there is no use putting it in mb ports.

So what i tried:
Removed GPU
Tested MB displayport and hdmi
Tested GPU displayport and hdmi
Swapped and reseated RAM
Did multiple CMOS clears via jumper
Verified board powers on but no keyboard response, no BIOS screen

As i understand this MB doesnt support BIOS flashing so what are my options?
Im student who uses it for my school work so i dont have much money to spend so i would like to keep mb change to last resort

Thank you.
