nvidia-smi is part of xorg-x11-drv-nvidia-cuda (fedora; rpmfusion) and nvidia-driver-cuda (rhel; cuda-rhel from nvidia) or xorg-x11-drv-nvidia-cuda (rhel, non-free rpmfusion), not the driver, and isn't available until install-cuda.

install-cuda needs be part of setup-system if nvidia-smi is going to be part of the driver identification.

an alternative way to detect driver presence and version: modinfo -F version nvidia
