使用AWS SNS時無法更新雲信息堆棧：主題資源

我已經創建了一個創建一個SNS :: Topic和其他資源的雲構建模板。現在的問題是，當我嘗試更新堆棧時，出現以下錯誤使用AWS SNS時無法更新雲信息堆棧：主題資源

"Update to resource type AWS::SNS::Topic is not supported"

堆棧策略是：

{ 
    "Statement" : [ 
    { 
     "Effect" : "Deny", 
     "Action" : "Update:*", 
     "Principal": "*", 
     "Resource" : "*", 
     "Condition" : { 
     "StringEquals" : { 
      "ResourceType" : ["AWS::SNS::Topic", "AWS::EC2::Subnet"] 
     } 
     } 
    }, 
    { 
     "Effect" : "Allow", 
     "Action" : "Update:*", 
     "Principal": "*", 
     "Resource" : "*" 
    } 
    ] 
}

CF模板是

{ 
    "AWSTemplateFormatVersion": "2010-09-09", 
    "Description": "......", 
    "Resources": { 
    "MySNSTopic":{ 
     "Type":"AWS::SNS::Topic", 
     "Properties":{ 
     "DisplayName": "", 
     "Subscription": [ ], 
     "TopicName": { "Fn::Join": [ "-", [ "Simple", "sns", "topic" ] ] } 
     } 
    } 
    }

有什麼（甚至hackable），我可以改變，讓aws完成aws更新堆棧而不刪除/修改sns_topic？
