You could try adding "modprobe.blacklist=nouveau" to the boot command
line.

Search the mailing list for similar reports in the past.

If you only plan to use Qubes OS on it, and not any other OS dual-boot system (not recommended to dual-boot with Qubes btw, but still may make sense for some use-cases), then you can just flat out disable nvidia grapghics in your BIOS/UEFI. That way you won't have to bother with Grub or EFI settings. Also even if you dual-boot, onboard graphics is often more than enough for most things, unless you plan to game or run really high-end graphic applications.

You will eventually have to solve it though if you want to use that nvidia in Qubes 4.1. (assuming GPU pass-through to specific AppVMs) makes it to the final 4.1. release version. But it'll take a good while before we see 4.1. as 4.0 is barely out of the door yet.

But you can try disable it in UEFI/BIOS to get started, if it works then you're also more sure that nothing else is preventing Qubes from being installed. If nothing else, it'll at least single out where the issue is, even if you only temporary disable it in UEFI/BIOS.

btw, you need to use "Tab" key on the installer, not the "E" key. Once Qubes is installed however, it's the regular old "E" Grub again. But during the installer, you need to use "Tab", screen will not change but 3 or so lines appears at the bottom of the screen, where you can add the driver blacklist at the very end (remember to add a proper space before adding it).

Thanks for reply, still no luck, is it adding "modprobe.blacklist=nouveau" into boot menu? attached photo.

You need a space character at the end of "nouveau"!!

Your screenshot shows "modprobe.blacklist=nouveau_rhgb" - which is
wrong.
