Question Is there an option like "Destroy forever"

Hi all,
You know at the beginning of the game you show a message but you don't need it anymore for the rest of the game.
On the other hand the conventional method is that to make a Playerpref and create a logic like this;
if (Playerprefs.GetInt("ObjectToDestroy")==1 Destroy(ObjectToDestroy)
But I don't want to check the prefs for this simple operation I just want it to disappear forever and don't bother me/player anymore.
Is there a method for this?

 

There is no method other than saving the data in a persistent place somewhere and deciding whether to instantiate or destroy or whatever with it.
