Hi David,
Sure, that is possible with both the vertical layouts (like the one on https://www.wellkinhospital.com/find-a-doctor/) as well as the isotopic layout (like the one on https://ajaxsearchpro.com/staff-search-filter/ ).
Vertical layout
Just change the results viewport option to a high number, so the scrolling never occurs on the box: https://i.imgur.com/mDcyzNk.png
Isotopic layout
Changing the number of rows is the key: https://i.imgur.com/FCZoOhr.png
In these cases the container will not trigger a scroll nor pagination, instead it will push the content down, and the browser scroll bar will trigger automatically.
