Can't launch installer in EFI mode

[gunnar...@gmail.com]

When I launch the installer in EFI mode instead of legacy, I get a block of text at the top left of my screen then the screen just goes black, the computer stays on though.

I tried adding "nouveau.modeset=0 rd.driver.blacklist=nouveau video=vesa:off" to my BOOTX64.cfg and that doesn't work. If I use Qubes 3.2.1, I get to the grub menu but eventually have a different problem that prevents me from installing (I want to install 4.0.1 so I didn't try for long).

I'm on a Dell G7 15

Is anyone able to help? I can show a video of what happens when booting the usb if needed.
