aws-cloudformation - 使用 Cloudformation 更改卷的 snapshotid

Question

我需要更改使用 Cloudformation 中的变更集创建的卷的 snapshotid。

这是我的代码

loggingVolume:
    Type: AWS::EC2::Volume
    DeletionPolicy: Snapshot
    Properties:
      AvailabilityZone:
        Fn::ImportValue: !Sub "${VpcStack}-subnet1AZ"
      Encrypted: true
      Size: 30
      SnapshotId: !Ref SnapshotID
      VolumeType: gp2
      Tags:
        - Key: Name
          Value: !Ref "AWS::StackName"
        - Key: Env
          Value: !Ref Env
        - Key: Geo
          Value: !FindInMap [Geo2Region, !Ref "AWS::Region", geo]
        - Key: Scope
          Value: private
        - Key: Role
          Value: logging

当我更改模板中的 snapshotid 并提交变更集时，出现以下错误:

Volume properties other than AutoEnableIO, type, size, and IOPS cannot be updated. Change the properties back to previous values and update the stack again.

如何更新卷以使用不同的 snapshotId
