PvE is a lesser used setting in Rust because the game is built upon PvP and raiding other players. Some mods can make PvE a bit more fun by introducing new events and mobs as well, but we don't recommend using PvE by itself. These steps show you how to switch your server to PvE.
1. Open the File Manager
2. Navigate to /server/docker/cfg/
3. If it isn't already there, right click and create a file called server.cfg
4. Add the line server.pve true
then save the file
5. Restart the server
