Here are some issues that I encountered installing Nvidia drivers on Fedora 33.
Nouveau drivers
Error:
The Nouveau kernel driver is currently in use by your system. This driver is incompatible with the NVIDIA driver,
and must be disabled before proceeding.
Solution:
echo 'blacklist nouveau' >> /etc/modprobe.d/disable-nouveau.conf
Kernel Headers
Error:
Your kernel headers for kernel 5.10.21-200.fc33.x86_64 cannot be found at /lib/modules/5.10.21-200.fc33.x86_64/build or
ln. /lib/modules/5.10.21-200.fc33.x86_64/source.
Solution
648 sudo yum groupinstall 'Development Tools'
649 sudo yum install kernel-devel

Solution
Make sure your version is downgraded to the one that is matching the one specified in make.log
After the install I believe you should reboot
