Source on that? Even the Tajectory Correction Maneuvers (TCMs) are planned in advance, and it's just the details of the TCM that are finalized in the lead-up to those events.
As far as the final approach goes, the core sequence started July 7[1], and no adjustments were made to it. They even had a TCM opportunity before that in case of a possible collision, that I heard was skipped.
