Explanation

To blacklist a module, you have to add the following line to the specified configuration file in the /etc/modprobe.d/ directory as root: blacklist <module_name> where <module_name> is the name of the module being blacklisted. You can modify the /etc/modprobe.d/blacklist.conf file that already exists on the system by default. However, the preferred method is to create a separate configuration file, /etc/modprobe.d/<module_name>.conf, that will contain settings specific only to the given kernel https://access.redhat.com/documentation/en- us/red_hat_enterprise_linux/6/html/deployment_guide/blacklisting_a_module
