Hi and welcome @global!
I don’t think it is possible to hide summary on shared view ONLY (and keep it still visible on that view in the base).
A simple workaround is to duplicate the view you want to share and in that new view click on the summary and select the option “none”. Then you can share that new view.
That way, on that new view there will be no summary visible, but still there on the original view for those that work within the base and have access to that view.
