I'm afraid, the vulkan stuff has not been widely tested, yet.

Is it still checking whether vulkan were available (loading the vulkan
loader library might be sufficient)? Otherwise I don't see how this
could be related ...

Sounds like a plan :-)
And given the recent CVE frequency, we might need a newer upstream at
that time, too :-(

I had a look at the nvidia-installer source and could not find anything
that updates the json files. And since there is only one json variant
shipped, I'm curious how the modified one comes into existence.

I haven't tried an installer-based installation in a chroot in a long
time ...

In the worst case, we could have the nvidia-vulkan bits conflict with
the non-glvnd nvidia libgl1.
