I don't know about your 2021 G70, but the antenna for the (now obsolete) 3G modem in my 2018 G18 is actually in front of the infotainment system inside the dash, so not trivial to get to. The shark fin antenna (in my case at least) is not used for that system, just XFM and GPS.... I think about the only sure way is to disconnect the modem antenna lead. I might just do that to be sure.
