According to the NASA Administrator if the crew had been present, yes.
"This anomaly has to do with automation," Bridenstine said. "Nicole
[Mann] and Mike [Fincke] are trained specifically to deal with the
situation that happened today, where the automation was not working
according to plan."
Presumably this means that an onboard crew could reset the Mission Elapsed Time (MET). That was certainly the case for Shuttle, although it was not a trivial task.
(I personally am curious as to whether the MET displayed onboard to the crew was in error. It was prominently displayed in the Shuttle cockpit. If so, the error might have been caught by them very quickly.)
However, the Administrator's comments refer only to the MET software error, and were made before the recent revelations of another software error later in the mission that would/could have caused a collision between the crew module and service module at service module jettison.
Assuming that the second problem had not been identified prior to jettison, and in the absence of Mission Control commanding, the crew could have done nothing about that error.
