Well that's surprising. The driver is there alright if look into
/lib/modules/$(uname -r):
./updates/nvidia-drm.ko
./updates/nvidia-modeset.ko
./updates/nvidia-uvm.ko
./updates/nvidia.ko

lsmod | grep nvidia:
nvidia_drm             57344  16
nvidia_modeset       1114112  11 nvidia_drm
nvidia              19968000  936 nvidia_modeset
ipmi_msghandler        65536  2 ipmi_devintf,nvidia
drm_kms_helper        217088  2 nvidia_drm,i915
