Disable Trigger on Active Standby Database

Hi,

we use dataguard and I want to know if it is somehow possible  to disable an after servererror on database trigger on the active standby database?

I can check with an SQL if I am on the PRIMARY or PHYSICAL STANDBY db but this produces additional overhead e.g.  always execute -> SELECT database_role  FROM v$database;

The trigger can't insert the error in a table anyway because the standby db is in open mode -> READ ONLY WITH APPLY, so the trigger itself always fails. Is there a way to disable it?

thx
