So this confirms that Boruto can awaken the Byakugan and hide it unlike the Hyuga clan. THIS IS GENIUS KISHIMOTO. And it makes perfect sense too.

Sage Chakra has the ability to give a non Uchiha the Sharingan in both eyes(Kakashi). So combining Naruto's SP chakra with Hinata's bloodline and you have kids that can turn the Byakugan on and off as if it were the Sharingan.
