It's a shame to lose a mature tree for the sake of a driveway, but yes, tree roots and pavers are not a good match. Beside root length, they expand in girth and can lift and displace the pavers.

If you value the tree, consider alternative routing of the driveway, or root pruning and installation of a root barrier.
