Hi,
have you seen this old Post: New install for Fedora 33 with Nvidia videocard - #12 by bachenberg
The biggest problem with NVidia are the many different solutions to the Problem, but you cant mix them.
Please remove every NVidia driver first: sudo dnf erase '*nvidia*'
and then only use the RPMFuision Repos and drivers.
sudo dnf install https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://mirrors.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
sudo dnf update -y # and reboot if you are not on the latest kernel
sudo dnf install akmod-nvidia # rhel/centos users can use kmod-nvidia instead
sudo dnf install xorg-x11-drv-nvidia-cuda #optional for cuda/nvdec/nvenc support
