You can place this testing into select_node event and see if you need to unselect something. E.g. the code below tests if there is more than one node selected and unselects the first one. Check demo - codepen.

.on('select_node.jstree', function(e, data){
      var countSelected = data.selected.length;
      if (countSelected>1) {
        data.instance.deselect_node( [ data.selected[0] ] );
      }
})
