Nope. But I don't think that was ever the intent.
At this point The Marvel executives have to know just how important T'Challa is to the BP comic book franchise (although you wouldn't be able to tell from the recent state of the character) but not so much to the BP movie/Disney franchise, as they tend to just follow where the most money will take them. So yes, Shuri will be BP for this interim film but chances are they will use all their hype and power to bring back a male BP, if not T'Challa himself, for the third film. The Press for which will be galactic.
