For included files, you can open their properties (using the three-line menu in the asset browser) and untick all platform checkboxes for them. These are supposed to be unticked after importing the extension, but something happens sometimes somewhere along the way.
If that doesn’t do it, you can move the GMLive folder out of datafiles to sit in your project folder - it’s not in Included Files because it has to be there, but because this is the easiest way to bundle some files that will be easily observable by the user and will update when you re-import the extension.
Ultimately, flipping live_enabled to false (manually or using a configuration - see above) is the only thing that matters here. The server the simpler part of the extension and isn’t useful on its own.
