I did use arch-chroot, and as I said, nvidia-inst doesn’t work under chroot, it first complains about not being able to run as root and when I run it under su I get libkmod and systemd related errors:
[root@EndeavourOS /]# nvidia-inst
2023-07-26 14:37:17: Error: This program must be started as a non-root user.

To use arch-chroot I mounted my system partition under /mnt and my efi partition under /mnt/boot/efi, then ran arch-chroot /mnt
