Suppress admin menu on batch page

I use Admin menu module. This code in views_data_export.module can suppress admin menu on batch page:

/**
 * Batch API callback.
 * Handles all batching operations by executing the appropriate view.
 */
function _views_data_export_batch_process($export_id, $display_id, &$context) {
  // prevent show admin menu on batch page
  if (module_exists('admin_menu')) {
    module_invoke('admin_menu', 'suppress');
  }
...
