NID Cookie and German Privacy Policy

Hello! The result of running a cookie bot was that my joomla site has a cookie called NID, which seems to come from Google and is used e.g. for Google Maps. I unpublished that module anyway, because i don't need it, but the cookie still shows up in the report. To get a legally compliant privacy policy i need to get rid of that cookie. I couldn't find source code in the module, not even with a deactived system editor (set TinyMCE to None!) . I searched in the plugins too, but couldn't find anything. Since the template Pure uses the Google Map Plugin i am thinking the cookie is coming from that. Yes, it seems to be standard Joomla administration or programming knowledge, but could i get a tip anyway? Because then my site is ready! Thanks in advance!!!

Hello, we dont use any plugin to show a map.
Its just the map source code in a module.

Anyway, the cookie bot identifies the NID cookie. That seems to come from google. I tried to search for the google map source code in the module list, but didn't find it. Not even in the module which was titled with "google "or "map". I also switched to source code view but found nothing. In which module would i find the source code for the google maps? Thanks in advance.
