I don't think this is possible to do. If a Hotlink is placed, it will be loaded into the Project.
I guess you would like a function similar to what we have with the "Unload" button in the XREF Manager Dialog.
I was thinking about this but I am not sure this would be a good idea in case of Hotlinked Modules, there are just too many things that could go wrong if there was such a feature. Just think about it: hotlinked module loaded, its content is labelled, dimensioned (both associative), then you (or a not-so knowledgable user) unload the Hotlinked Module. All those labels and dimensions are lost and must be redone.
In any case, if you think this is important, please create a Wish and post its link in this thread.
