Unable to switch to UEFI due to GOP problem

[0Nameduser]

There's a program I'd like to use called RTCV (Real Time Corruptor), but for being able to use RTCV requires Vanguard to connect (hence the "V"). Attempting to use RTCV shows "Waiting for Vanguard client to connect" but stays like that forever. Searched up the problem, one from reddit said to "Enable Secure Boot" to a guy that had a similar problem like me.
Attempting to enable said secure boot, requires UEFI. Attempting to switch to UEFI, the PC restarts to switch. It goes on, suddenly it shuts down. Restarts again,

"There is no GOP (Graphics Output Protocol) support detected in this card.
'BIOS CSM/UEFI Mode' settings in BIOS will be changed to 'CSM'.

Press F1 to run setup.
Press F2 to load default values and continue."

All while there's a bright white light shining from where it says "VGA" below it.

Searched up the GOP problem, returns "Find a switch for the GPU or flash a new VBIOS on it".
No switch found, and flashing the VBIOS didn't help at all, same GOP message.

GPU-Z says the GPU supports UEFI, in other words there's a checkbox checked where it says "UEFI".

+ I have a UEFI-Compatible Intenso 1TB USB Hard Disk on GPT (GUID Partition Table) to boot on with UEFI (Windows not installed yet).
I also attempted to update the Motherboard BIOS to vAE but downloading it returns to "Not Found".
What I find weird is that first time switching to UEFI, it booted to the UEFI USB Drive. Switching to UEFI again, same GOP message.
Please help, nothing I searched did anything.
