No we can't do that for various reasons.
When we finally have POI filtering (and unfortunately it appears that we won't have it yet for GU51) it should be possible to just filter out the links. We already made it so that we put the links in a separate file so you can permanently remove them if you want. Replacing map_links.xml in UI\<YourCustomUI>\POI\ with an empty file and making it read only would achieve that if you want.
