The CDI generator aborted with "failed to initialize NVML: Driver Not Loaded", taking docker.service with it (requiredBy) and failing the switch. Two causes. The nixpkgs NVIDIA module only adds nvidia/nvidia_modeset/ nvidia_drm to boot.kernelModules when services.xserver.enable is set, which is false on this Wayland-only host, so load them explicitly. nvidia_uvm stays out: the module's modprobe softdep loads it once the GPU device exists. The generator also runs during activation, when a module rebuilt against a new kernel cannot be loaded until reboot -- a guaranteed failure after every kernel bump. Guard it with ConditionPathExists on /proc/driver/nvidia/version so it skips rather than fails; the toolkit's udev rule restarts it when the device appears, so the specs are generated on the next boot.
