To disable a service, you must be root or have sudo privileges.

For example, to disable the Puppet service, you would run the following command:

svcadm disable network/cswpuppetd:default

This will disable the Puppet service and prevent it from running.

To verify that the service has been disabled, you can run the following command:

svcs | grep puppet

This will list all of the services that are currently running, and if the Puppet service is disabled, it will not be listed.
