Well, in Conquest you kill Garon, who does have most of Anankos' power, but no. And Takumi is just possesed.
In Birthright, you also kill Garon, so no.
In Revelations, you kill the mad form of Anankos but you never kill the soul of Anankos I think? Y'know the one in those DLC ones about hidden truths or whatever
So I don't know but probably not.
