The rules require unanimous consent to suspend the normal rules, but they can, and do, suspend the unanimous consent rule by majority vote.

Just for one notable example of overcoming the unanimous consent rule, take the ending of the nomination filibuster.

They certainly didn't have unanimous consent, as there was a filibuster in the first place, so they just bypassed the unanimous consent rule itself.
