Given that it is 27 billion kg (roughly 60 billion pounds), and would create a 880 megaton blast, it is carrying a lot of energy to deflect. The best you could is fire some nuclear warheads to fracture the thing into some smaller pieces, but even that would be problematic.
Don’t need to (or want to) break it into pieces.
Just alter its course a bit (an inch per second difference in its velocity, for example) in the next year or two and that velocity change will then have a decade or so to put it somewhere significantly different when Earth gets to that neighborhood in 2029.
A few centimeters-per-second velocity change in the next year could do the job.
