exactly the databooks never once mention any other kekei genkei EVER

the manga specifically says when naruto asks what the byakugan is this

the byakugan is one of the advanced blood abilities passed down in the hyuga house its an eye ability similar to the sharingan but in terms of ability of insight it surpasses the sharingan

this doesn't mean they have multiple i take this as they are saying that the byakugan is one of the advanced blood abilities, its passed down in the hyuga house

there was never any other instance where they ever talk about the hyuga having more than one kekkei genkei this statement i quoted above is simply saying the byukugan is one of the advanced blood abilities ie one of the many that exist in the world its not saying the hyuga possess more than one
