Really need some additional information. Is this specific line in a config file? If so which service/application? If its a configuration file using templates is a great way to create custom changes. If its a common application there are many public cookbooks that can assist with this as well. A great example is the ssh-hardening cookbook.  
There are literally dozens of resources out there for managing various subsystems on servers.
