Is it possible to disable the sending of messages from MapShare web only with satellite coverage?

The situation would be:

- Before the trip I have activated in "Social" the possibility of being sent messages during a long trip in which I will be without land coverage (maybe yes, but usually no)
- I have given the URL and password data access to MapShare web to trusted people, but it is possible that it reaches other people
- Suppose I start receiving many messages (which I pay €0.55) that I don't want. I can tell them not to message me, but...

Is it possible to deactivate that sending of messages or even deactivate Mapshare through the inReach (Mini 2 in my case) or through the Explore app of the mobile connected by bluetooth to the inReach? (I'm assuming there is no ground coverage and I can't access explore.garmin.com to turn it off).

I've been looking at all the options and I don't think is possible, but does anyone know of a way to do it?
