To add to this issue, it is timing related. We release nvidia dkms
drivers, which can be installed by themselves, but this means module
compilation on the machine so it breaks secure boot. Therefore we also
create Linux Restricted Modules (LRM) that are nvidia drivers
precompiled by us against all kernels and signed so when installed they
don't break secure boot. Now, nvidia drivers are released to -proposed
before LRMs are built. This creates a window when someone using ubuntu-
drivers may install nvidia dkms drivers and not LRM drivers, resulting
in their system having secure boot disabled, which is not an option for
cloud environments. Another windows of opportunity to trigger this is
during publication to the archives. A dkms drivers may already be
published but LRMs for the specific kernel are not there yet. The
decision was made that dkms drivers should not be available to be
installed by accident so hidden behind a switch. An advanced user would
use it, therefore ensuring that they know what they're doing.

Due to timing related nature of this issue, testing it in real world
scenario would require timing the verification to a few hour window once
a fortnight or so (varies), therefore to force it, an extra PPA with a
newer driver is created.
