Yes, an Application Data Sheet (ADS) can be used to correct or update inventor information. The MPEP 601.05(a) states:

A corrected ADS may be submitted to correct or update information other than the inventorship. A corrected ADS correcting or updating information other than inventorship which is also reflected in the oath or declaration under 37 CFR 1.63 filed in a pending application must be accompanied by a request to correct or update the information under 37 CFR 1.48(c).

To correct inventorship, a request under 37 CFR 1.48(a) is required along with the corrected ADS. It’s important to follow the proper procedures to ensure the changes are accepted by the USPTO.
