Or making an array null or full based on a boolean configuration:

   Feature_Present : constant Boolean := False;  -- change to true
   Size_Of_Array : constant := 100_000;
   The_Array : The_Array_Type (1 .. Boolean'Pos (Feature_Present) * Size_Of_Array);
      -- null array if feature is not present
