Are you using an alternate repo to get the NVidia module rpm's? If not, log in and run the following:
rpm -Uvh livna-release-8.rpm
yum -y update
This will download the rpm for the livna repo, install it, and then use it to get the NVidia module updates.
If you are already using the livna repo, then I'm not sure why it isn't working. Perhaps you just need to install it with
yum install kmod-nvidia
Once you get the livna repo working and the nvidia kernel modules installed, pup should warn you about future updates.
