Rotate and Drag Problem

I am moving my object with onDrag, but there is a situation like this: I do not want to execute a drag if the sprites are rotated, but if the sprites are not rotated, I want drag to be executed. The Unity 2d code is shown below.

 if( !drag )
 {
     if( rota<13 )
     {
         rota = rota + 0.5f;
         //rectTransform.anchoredPosition += eventData.delta;
         mPosDelta = eventData.delta - mprevpos;
         transform.Rotate( 0 , 0 , rota , Space.Self );
     }
     else
     {
         this.transform.rotation = Quaternion.Euler( 0 , 0 , 180 );
         Invoke( nameof(Wait) , 3f );
     }
 }
 else
 {
     rectTransform.anchoredPosition += eventData.delta;
 }
