Disable loading kernel modules

Hi,

I am running CentOS 6.5 and I want to remove auto loading 8021q and garp modules, but there are no configure files in /etc/modprobe.d define bot modules.

I even added both module names to /etc/modprobe.d/blacklist.conf, both of them are still loaded after the reboot. How can I disable both modules from boot?

Code:
$ lsmod | grep 8021q
8021q                  25317  0 
garp                    7152  1 8021q

Thank you.

NAME
modules-load.d - Configure kernel modules to load at boot SYNOPSIS
/etc/modules-load.d/*.conf /run/modules-load.d/*.conf /usr/lib/modules-load.d/*.conf DESCRIPTION
systemd uses files from the above directories to configure kernel modules to load during boot in a static list. Each configuration file is named in the style of /etc/modules-load.d/<program>.conf. Note that it is usually a better idea to use the automatic module loading by PCI ID, by DMI ID or similar triggers configured in the kernel modules themselves instead of relying on static configuration like this. CONFIGURATION FORMAT
The configuration files should simply contain a list of kernel module names to load, separated by newlines. Empty lines and lines whose first non-whitespace character is # or ; are ignored. Each configuration file is named in the style of <program>.conf. Files in /etc/ overwrite files with the same name in /usr/lib/. Files in /run overwrite files with the same name in /etc/ and /usr/lib/. Packages should install their configuration files in /usr/lib/, files in /etc/ are reserved for the local administration, which possibly decides to overwrite the configurations installed from packages. All files are sorted by filename in alphabetical order, regardless in which of the directories they reside, to ensure that a specific configuration file takes precedence over another file with an alphabetically later name. EXAMPLE
Example 1. /etc/modules-load.d/virtio-net.conf example: # Load virtio-net.ko at boot virtio-net SEE ALSO
