Yes, Once you are already inside a loop on a repeater (a flex field is also a repeater) you no longer need to supply a post ID.

if (have_rows('flex-field-name', $post_id)) {
  while (have_rows('flex-field-name', $post_id)) {
    the_row();
    // you no longer need to provide the post ID
    // nested repeater
    if (have_rows('locations')) {
      while (have_rows('locations')) {
        the_row();
        // etc....
      }
    }
  }
}
