Why nothing about Apache Module mod_authz_host?

cPanel & WHM docs

In the cPanel & WHM documentation there is nothing about Apache Module mod_authz_host:

https://docs.cpanel.net/

Apache HTTP Server project

https://httpd.apache.org/docs/2.4/mod/mod_authz_host.html

The customer wants to block some Administration and Login areas for his website based on IP & Hostname. The customer wants blocking based on Hostname too because some of his employees do not have Dedicated IP, their ISP does not provide them with Dedicated IP, but instead the ISP provides them with Dedicated Hostname. So it requires mod_authz_host to achieve this:

Require all denied
Require host customer10842.isp.com

Also, this type of rules are not processed either:

<Files login.php>
     Require all denied
     Require host customer10842.isp.com
</Files>

In both EasyApache and CloudLinux I cannot find mod_authz_host to be available!
