Using custom JS, stuff that’s not listed in the docs

1) Enqueue your custom JS script on the acf/input/admin_enqueue_scripts hook

2) You custom script should depend on the acf script handle acf-input

3) You initialization code should look something like this

if (typeof acf != 'undefined') {
  acf.add_action('select2_init', function($input, args, settings, $field) {
    // $input (jQuery) hidden input element
    // args (object) args given to the select2 function
    // settings (object) settings given to the acf.select2 function
    // $field (jQuery) field element
    
    // you need to check the $field element to make sure your looking at the right field
    // you can use the console to see what's in vars
    // for example
    
    conole.log($field);
    
  });
}

I found this post on the select2 argument that you probably need to set http://stackoverflow.com/questions/19789984/limit-the-jquery-select2-maximum-selected-options
