I don't think so. The borders are 3D objects, and in the domain of the rendering engine. There is a method to toggle borders in the debug console, but it's wonky... it turns them off, but doesn't clear the frame. So you get a static image of the 3D borders imposed on the screen. Even if it did work correctly, I'm not sure it can be accessed with lua. If I find a solution, I'll include it in an update. edit: @bostonbongrips Looks like it's tied in with the hex grid. If you issue "toggle overlay cultureborder", followed by "toggle overlay hexgrid", it removes it completely. I still don't know whether you can call these from a script, but it works from the console.
