Setting: "subscription to the users node" in the control panel.

Hello.
I need to disable the opportunity to subscribe to a specific users node.
To do this, I remove a few lines in the files:
subscriptions_taxonomy.module:

function _subscriptions_taxonomy_node_options($account, $node) {
  $options = array();
  $vids_to_omit = variable_get('subscriptions_omitted_taxa', array());
  foreach ($node->taxonomy as $tid => $term) {
    // Taxonomy term
    if (in_array($term->vid, $vids_to_omit)) {
      continue;
    }
    $options['tid'][] = array(
      'name' => t('To posts in %term', array('%term' => $term->name)),
      'params' => array('value' => $tid),
    );
//    $options['tid'][] = array(
//      'name' => t('To posts in %term by %name', array('%term' => $term->name, '%name' => $node->name)),
//      'params' => array('value' => $tid, 'author_uid' => $node->uid),
//    );
    $options['tid']['weight'] = -1;
  }
  return $options;
}

subscriptions_content.module:

function _subscriptions_content_node_options($account, $node) {
  // Default node, field are the first three indexes, but they can be overridden in params
  // Thread
  $options['nid'][] = array(
    'name' => t('Subscribe to this post'),
    'params' => array('value' => $node->nid)
  );
  $options['nid']['weight'] = -4;
  $unlisteds = variable_get('subscriptions_unlisted_content_types', array());
  if ((user_access('subscribe to content types', $account) && !in_array($node->type, $unlisteds)) || user_access('subscribe to all content types', $account)) {
    // Content type
    $type_name = node_get_types('name', $node->type);
    $options['type'][] = array(
      'name' => t('To %type posts', array('%type' => $type_name)),
      'params' => array('value' => $node->type),
    );
    // Content type and author
//    $options['type'][] = array(
//      'name' => t('To %type posts by %name', array('%type' => $type_name, '%name' => $node->name)),
//      'params' => array('value' => $node->type, 'author_uid' => $node->uid),
//    );
    $options['type']['weight'] = -2;
  }
  return $options;
}

Please make such a setting: "subscription to the users node" in the control panel.
