Thanks, I found the keys. Now the only issue is that it says there are 4 errors when only two of the 4 entries are duplicates. It puts a red flag on each of the 4 fields.

Example:
gallery_id: network
gallery_id: network
gallery_id: automation
gallery_id: security

 add_filter('acf/validate_value/key=field_58d453ce55ea1', 'acf_unique_repeater_sub_field', 10, 4);
function acf_unique_repeater_sub_field($valid, $value, $field, $input) {
  // set up an array to hold all submitted values for rows
  $list = array();
  foreach ($_POST['acf']['field_58bbc19f95a04'] as $row) {
    if (in_array($row['field_58d453ce55ea1'], $list)) {
      // this one already exists
      $valid = 'There are duplicate '.$field['name'].' values';
      // found a duplicate so we don't need to continue looping
      break;
    }
    // add the value of this row to the list
    $list[] = $row['field_58d453ce55ea1'];
  }
  return $valid;
}
