Here is a rough outline of what you need

$repeater = 'field_XXXXX'; // field key of repeater
$value = array(
  // nested array for every row of repeater
  array(
    // field key => value pairs for each sub field
    'field_XXXXX' => 'block title', // title field
    'field_XXXXX' => array(
      // nested repeater
      // field key => value pairs for each sub field
      'field_XXXXX' => 'link title',
      'field_XXXXX' => 'link url',
      'field_XXXXX' => 'link fa icon',
    ),
    // next row in nested repeater
  ),
  // next row in repeater
);
update_field($repeater, $value, $post_id);
