Will Boruto be able to awaken Byakugan?
From trivia here, it is stated that Masashi Khisimoto forgot to give Byakugan to Boruto and Himawari.


  Boruto and Himawari Uzumaki, despite being children of Hinata Hyūga,
  do not have the characteristic white eyes inherited by Hyūga
  descendants.  According to Masashi Kishimoto, he simply forgot to give
  it to them.


Later he corrected this. But so far, only Himawari has Byakugan.


  Kishimoto later corrected his mistake for Himawari by giving her the
  Byakugan in the Zai no Sho's special chapter The Day Naruto Became
  Hokage.  While activated, her eyes take on the normal characteristics
  of the dōjutsu. When not in use, she has her original blue eyes.
