Change Port of Dashboard

I’ve got the node red editor and the dashboard up and running. Now I want to allow other people to enter the dashboard. But since I want to prevent other people from modifying the program, I would like to change the port on which the dashboard can be accessed. Is there an easy way to do this in Node-Red?

I don’t beleive you can have two different ports but you should read about security https://nodered.org/docs/security
