Yes, Boruto and Himawari have a fragment of Kurama's power in them. The whiskers are a clear proof of it. While being the Nine-Tails' jinchūriki doesn't necessarily grant whiskers, beign influenced by Kurama's power does.

But I don't think Naruto's sons can enter any of their father's modes, unless they're given some more chakra from the Nine-Tails or trained in some way.
