There is no planet Nibiru. The descriptions and forecasts that involve that entity
are internally inconsistent and self-contradictory, have changed drastically during
the 20 years or so since they began, hold a place of honor in the body of popular
but baseless stuff known as "pseudo-" or "junk-" science, and are uniformly discounted
by the real scientists who have any idea of what they're talking about.
There is no "Nibiru planet". Nibiru is a word used in Babylonian astrology; it's really unclear what exactly it refers to: in some places, it seems to be used to refer to Jupiter, in other places Mercury, and in some it apparently means a region of the sky and not a planet at all.
Since Nibiru does not exist, you don't have to do anything.
