The book neither confirms nor denies that the chakra of the nine tailed beasts is involved in obtaining Six Paths Senjutsu, so in other words it's still open to interpretation. It does, however, confirm that Naruto received his Six Paths Sage Mode from Hagoromo.

Even Shikamaru Hiden claiming Naruto became a pillar for the Ten-Tails' power doesn't explicitly state that the power he obtained from the beasts was Six Paths Senjutsu. On the other hand, Hagoromo appears to have possessed the Six Paths Senjutsu (or at least the Truth-Seeking Balls) from birth, so I don't see any reason to assume his chakra alone isn't enough to grant Naruto that power. Just like his chakra could immediately grant Sasuke the Rinnegan, whereas Madara's method of combining the sons' chakra took decades.
