let me know if you have any questions

add_filter('acf/load_value/name=add_on_repeater', 'prepopulate_add_on_repeater', 20, 3);
function prepopulate_add_on_repeater($value, $post_id, $field) {
  if (!empty($value)) {
    // already has a value, do not overwrite
    return $value;
  }
  
  // do a query to get all posts of the post type
  $args = array(
    'post_type' => 'add-ons', // your post type
    'posts_per_page' => -1, // -1 get all
    'fields' => 'ids', // return only list of IDs
  );
  $query = new WP_Query($args);
  if (empty($query->posts)) {
    // no posts found
    return $value;
  }
  
  // initialize value, a repeater has an array value
  $value = array();
  
  // loop over posts and built repeater value
  foreach ($query->posts as $add_on_post_id) {
    // each row of the repeater is a nested array
    $value[] = array(
      // you must use field key to set value of sub field of each row
      'field_XXXXXXX' => $add_on_post_id
    );
  }
    
  return $value;
}
