With their recent Unity Hub 3.13.0 upgrade, they have removed the option for not connecting a project to the Unity Cloud. Because all that yummy data, I guess…

This is how to setup a project without uploading everything to Unity’s servers:

1. If you want to use a project template you’ve not used before, create a dummy project with that template (which will be uploaded to the cloud). Give it a funny name, maybe
2. The template will be downloaded to your local app data
   • Windows: %APPDATA%\UnityHub\Templates
3. In that folder you find .tgz archives for each template. Select the one you need and pull the contents of package/ProjectData~ out.
4. Place it into a new folder with your desired project name.
5. In Unity Hub, click “Add” next to the “+New project” button and add a project from disk
