You can use
enable_pagination='false' shortcode option to disable the pagination … I’m guessing that is what you want to do, right? I do not recommend doing this if you have more than 40–50 entries to display though as the more entries being shown the more impact there is on page load time. This is not a Connections limitation … it is basically for the same reasons WordPress limits 5–10 posts per page.
Hope that helps!
