Deletion of audit trail entries

I would like to know, if it is possible to delete audit trail entries which are empty but have a timestamp. This occurs during case processing by the user or agent. is it possible to establish a filter criteria and delete this enties in the audit history table?

The next question, is there an OOTB activity that can be used to delete this entries?

Thanks in Advance

There is an OOTB decision tree called FilterHistory in Work- class which decides which audit to print. The conditions set to true will be considered for printing. You can save it to your work class and customize it as per you requirement.
