Pro version - Google Analytics Tag

There appears to be a Google Analytics tag/Manager you are adding to all our docs pages. This tag appears to add a whole bunch of analytics tags and ads tags within it (google, doubleclick etc).

The Tag ID is www.googletagmanager.com/ns.html?id=GTM-TNGJT5N

Is there a way to remove this tag from our pages?

Due to GDPR we need to be able to get consent from the user to set cookies (as its also appears to come from one of our domains). We have a cookie management solution so can add it in there if you require it for your own reporting, we do however need to have the ability to control it.

Thanks for the help.
