Audit trail - create only one delete trigger

Hello,

I would like to use AUDIT TRAIL on EBS 11.5.10.2 with only a trigger for delete actions on one table of the AR module.

But this tool  always creates triggers for delete, insert and update actions (i have not seen any option allowing to create only a delete trigger).

So what do you think about the 3 following workarounds:

1 - Set the insert and update triggers to invalid status.

or

2 - Update the code of the insert and update triggers so as each one does nothing.

or

3 - Drop the insert and update triggers

Note the database is monitored by Oracle On Demand.
