Cassandra and JMX port usage

As per the Apigee doc, JMX port is enabled by default for Cassandra. It is Intriguing to explore further on the below questions:

1. JMX ports are by default used for monitoring, but does it allow any actions which are mutable

2. By enabling authentication on JMX port, are there any utilities of Apigee which work on the JMX port? For e.g. NodeTool - is this a utility which uses JMX port

3. Is it possible to disable the JMX Port. Docs below references enabling credentials for JMX port but not to disable the port altogether.

4. If it is possible to disable, what is the impact of disabling the JMX Port
