Only upgrading Senju Sage Mode do you get Hagoromo's Sage Mode. Madara got Senju Sage Mode from Hashirama, but due to Madara not receiving upgrade chakra straight from Hagoromo, his Senju Sage Mode will take some time to upgrade, just like his Rinnegan.

But this is based on my speculations though.

What if the Rinne on the stone tablet is actually referring to the Rinne Sharingan on the Ten-Tails, or in other words, the person that became the Ten-Tails' jinchuriki can awaken the Rinne Sharingan. After all, the Rinnegan is only used to unseal the Six Paths: Chibaku Tensei, so technically one can awaken the Rinne Sharingan without the Rinnegan, right?

By the Ten-Tails' jinchuriki, I mean the chakra of all Tailed Beasts plus the Demonic Statue of the Outer Path.
