Yes, please install yum-plugin-elrepo which will fix the 'issue' for you.

Yum is telling you that it can not install the latest kmod-nvidia 
version because it requires the CentOS 7.7 kernel, which is not yet 
available to you.

By installing yum-plugin-elrepo, the plugin will mask (hide) from yum 
any kmod package which requires a kernel which is not available to yum. 
Once the CentOS 7.7 kernel becomes available to you, yum will then also 
see the corresponding kmod-nvidia update for that kernel and you will be 
able to update as required.
