Public bug reported: So if Canonical set https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa repo why Canonical isn't sign drivers in this repo to use them in UEFI enabled system???!!?? You force CONFIG_EFI_SECURE_BOOT_SIG_ENFORCE to yes in your kernel config but you don't have any solution for unsigned kernel modules, like NVidia or VirtualBox.
