Lirespeed conf rule to block file "xmlrpc.php"

We host a large number of WordPress files on our servers. For security reasons, I would like to block access to the file: xmlrpc.php

I can add a rewrite rule into each site’s vhost.conf file.

In order to avoid adding a file into each vhost.conf file, I would like to add a single rewrite rule to the main file: httpd_config.conf

Can someone suggest the correct rule to add.
