Cannot boot High Sierra installer, prohibited sign

So I was able to get the Installer to boot and install by disabling integrated graphics in BIOS, but there's no option to disable the NVIDIA GPU. I tried following this guide: https://www.tonymacx86.com/threads/...-only-ran-for-0-seconds-with-dual-gpu.233092/ and found that my _OFF method was in the same scope as in the example, so I created SSDT-DiscreteSpoof.aml. I still could not boot with that, but I could boot my main drive (sata ssd, I added SATA-100-series-unsupported.kext in Clover/kexts/Other) using the Nvidia GPU. However, USB does not work nearly all of the time. I think I can figure out the GPU issues if I get the USB issues figured out.

See USB guide:

FYI: I think you'll have better luck getting the IGPU to work vs. the Nvidia (but it looks like you disabled it from BIOS).

I was surprised that there was no way to disable the Nvidia GPU from the bios, but I couldn't boot with both the iGPU and dGPU enabled because of the Windowserver bug. I thought that my custom SSDT to disable the dGPU matched the one in the guide, but I still never get a lock screen if I re-enable the iGPU and boot with it. I'll try the USB guide and see if that helps. Thanks!
 
I updated my config.plist with the HD630 one you linked, but now I get stuck at: IOConsoleUsers: gIOScreenLockState 3
This message alternates with a white block at the top right of the screen.

I tried booting with a fake platform-id and also tried disabling lilu.kext and intelgraphicsfixup.kext, but I had the same issue each time.

I can't boot at all with the iGPU enabled in bios, so I can't provide any of those files, but my Clover folder hasn't changed except for updating to the new config.plist (linked here https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/) since this post:

You need to provide a verbose boot photo and the EFI/Clover that produces it.
I cannot guess regarding changes you may or may not have made.
And I have no ability to see what the problem is unless you provide a photo.
