People are retarded. Naruto can use Lava Release only by 2 means:
 * having Son Goku mold Lava Release chakra for him
 * using it completely by himself through Six Paths Senjutsu (yet to do so)

Neither has to do with genetics. Naruto and Boruto don't have genes for Lava Release, the only way for Boruto to use Lava Release is if he would become Son Goku's jinchuuriki or get Six Paths Senjutsu.
