The CVT is not a serviceable part, not even Nissan technicians can service it, which is why bad CVT's are simply replaced with whole new units. One of the reasons for this is the belt requires and extremely high pre-load, in excess of anything that could be accomplished with the tools at any Nissan Dealership, so it can only be done at the time of manufacture.
So no, you can't mess with the belt, upgrade or otherwise.
