Following is a walkthrough on how to blacklist a kernel module. The specific example is blacklisting the nouveau driver so that I can install the OEM Nvidia driver.
1. First, blacklist the nouveau driver: Add a line to the textfile /etc/modprobe.d/nouveau-blacklist.conf that contains they keyword ‘blacklist’ and the name of the driver
blacklist nouveau2. Rebuild the initramfs image file. First, backup existing initramfs
mv initramfs-3.10.0-327.18.2.el7.x86_64.img initramfs-3.10.0-327.18.2.el7.x86_64.img_2016-06-09.bakBuild new initramfs
dracut -v /boot/initramfs-$(uname -r).img $(uname -r)3. Reboot the system and confirm that the driver in question is not loaded.
lsmod | fgrep nouveau
