Either way, Boruto received his Byakugan either by awakening due to the death of a close one (may be Naruto, but still currently unknown), or by implant (though this doesn't make sense). Kishimoto was intending to give him the Byakugan, but forgot. So this would confirm the fact that Boruto is capable of awakening the Byakugan after all, so he wouldn't need to have an implanted one. So the last option is awakening. Again, WE DON'T KNOW IF NARUTO IS ACTUALLY DEAD YET.
