IBM DB2 Timetravel logging based on some criteria
With Db2 (LUW) Temporal Tables, there is not any option to exclude updates from a certain user.

However, the SET_MAINT_MODE_RECORD_NO_TEMPORALHISTORY procedure is available, and can be called by a user (if a user is granted permission on it), and this will disable the recording of temporal history for system-period temporal tables with the the duration of the current session.
