CUDA Support for Blender

Hello, I am trying to get CUDA support to work under Blender on my Fedora 31 system. I have a supported graphics card and the packages xorg-x11-drv-nvidia-cuda-libs xorg-x11-drv-nvidia-cuda installed from the repository, but Blender still says that GPU rendering is not supported. I have seen references to Nvidia's "CUDA Toolkit". Is that needed above and beyond the two packages listed above? Is it available in a package from RPMFusion or do I need to get it from Nvidia? If it is the latter, can it be installed alongside the RPMFusion RPMs or will I need to switch to using Nvidia's packages? Thank you, Jay
