An Apache module that disguise or remove "Server: " HTTP header

Although sending the Server header in HTTP responses is not defined as a MUST in RFC 2616, the Apache HTTP Server does not allow you to disable sending this header via it's configuration. You can reduce it to "Apache" by removing the version, or the additional modules with the ServerTokens directive. Despite what some people are saying, even mod_headers can't suppress it.
