There are no vip commands.. Except if you count! vote kick and !voteban I think, but those can be done through the tab menue, so I would not categorize them as commands.
You can no-clip yes. Press "v" and you will be able to fly. As for commands you can Vote-Ban and Vote-Kick. Do not abuse them please. To find them hold Q and go to the top right of the menu and click the tab. You should see them
