[CentOS] Question on CentoS 7.4 on nvidia

So I removed the nvidia items and reinstalled.

In /var/log/messages I saw dracut commands for every kernel EXCEPT the
4.14.5 elrepo kernel.
So I did it manually and I get an error.

/usr/bin/dracut --add-drivers nvidia -f
/boot/initramfs-4.14.5-1.el7.elrepo.x86_64.img 4.14.5-1.el7.elrepo.x86_64
Failed to install module nvidia

No sure what to do.
