Yeah, thanks to everyone @dsanke , @chinobino and obviously you @Lost_N_BIOS

You're welcome, but my part was minimal
Maybe chinobino knows a way you can run that without having to jump through hoops at each startup?

@DarkPoe @Lost_N_BIOS

Glad you got it to work - it's a pity that it's a x4 PCIe slot and you have to use a modified driver.

When I was using SLI on a crossfire motherboard I had to disable driver signature enforcement and disable secure boot policy;

bcdedit /set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit /set TESTSIGNING ON

and to undo the changes;

bcdedit /set loadoptions ENABLE_INTEGRITY_CHECKS
bcdedit /set TESTSIGNING OFF

This should allow you to install your modified driver without it being blocked by Windows at each boot.

Yeah @chinobino that works too, but anticheat software will yell about it, like PUBG's and Valorant... So no go there

Yep the anti-cheat software issues are another reason I recommend using an SLI motherboard - too many hassles.

Although I completely understand you wanting to use what you already have, it's a pity that Nvidia aren't a little more flexible.
