How to avaid more if else in effective way

I have a function like blow but it seems more if else conditions .if there any similar effective way to handle the same .this function with my code properly working.

   public bool UpdateAdjustmentRequest()
        {
           if (ds1.Tables[0].Rows[0]["AppLev1Req"].ToString().Trim() == "True")
            {
