I hope you are talking about default generated select pages with list views Well i think u can do it using CSS by disabling the select checkbox of first child.
If you want to go pure mendix way get rig of that auto populated select page and degign it urself there based on conditions u can mostly meet all the requirements.
Hello Sebastian,
By default its not possible to remove the selection , There is a widget you can check https://appstore.home.mendix.com/link/app/27519/ I do not know if it will work with your latest Mx Version.
Thanks
