uhm I removed the repos of NVIDIA CUDA that I had under /etc/yum.repos.d.

Now I get this:

$ sudo dnf install akmod-nvidia

You have 3 different package versions conflicting.
470.74 from rpmfusion-nonfree
465.24 from (I think) rpmfusion-nonfree-nvidia-driver
and
470.57 from cuda-fedora33-x86_64

first uninstall all nvidia packages

sudo dnf erase *nvidia*

then verify that only the rpmfusion-free and rpmfusion-nonfree repos are enabled

sudo dnf repolist

If you still have the cuda or rpmfusion-nonfree-nvidia-drivers packages in that list then you need to either disable them during the install with --disablerepo or permanently disable them. I suggest permanently with

sudo dnf config-manager --disable <reponame>

then reinstall the nvidia packages.

sudo dnf install akmod-nvidia xorg-x11-drv-nvidia-cuda

That command should bring in the cuda drivers and all the most necessary of the nvidia drivers. Check to make sure all the nvidia packages are only being installed from the rpmfusion-nonfree repo.
If you are planning to suspend or hibernate then the power package also needs to be installed as shown here.
