How is Boruto going to take control over Momoshiki?

My take: Senjutsu aka Sage mode

Here are my points:

Point 1,

From episode 1 we are able to see that Kawaki's Karma didn't change at all, it kept it's original design just like kid kawaki, however, Boruto's karma design did in fact change, right now, you can see that it doesn't fully surround his eye, how come?

Point 2

Sage Mode, we have learned from the past that all sage mode users had marking at their eyes, now what if I told you that boruto's teenage karma design is both the karma seal and sage mode combined, stay with me, we are reaching the conclusion of this thread

We all know that the otsutsuki stand no chance whatsoever against nature chakra since they cannot absorb it and also cannot resist it.

To quote urashiki seeing mitsukis sage mode:

Now what if I told you that boruto will surpress momoshiki with the gracious deity gates? That senjutsu seals movement and we can see when boruto activates his karma in episode 1, it goes up very slowly and when it reaches his eye, the Jougan activates as well

Momoshiki, pinned down by senjutsu, and being watched over by the pure eye, if that isn't otsutsuki control, I don't know what is.
