Preventing kernel modules from being loaded at the bootloader / grub in CentOS 7 / RHEL

Although this will typically done with the mod probe there are situations where the need to disable specific kernel modules before loading the kernel are necessary. One such situation is while I was installing a fresh instance of CentOS on an older server.

At the CentOS bootloader select the relevant entry and hit tab. You should now be able to edit the Linux kernel (vmlinuz) boot parameters.

Simply append:

module_blacklist=<module_name>

and hit enter.

This should theoretically work on all modern kernels / distros - so is not just limited to CentOS / RHEL.
