Thank you @chetanb, that is a very helpful post. Although it confirms that ServiceNow has not made the Monaco editor configurable, and any solutions to try and configure it comes from third-party plugins.
I hope ServiceNow adds the ability to pass configuration options, should be easy enough to do global config with a system property and user level config with user preferences.
I'll mark your reply as the solution and revisit the Monaco configuration at a later time.
