Updating TimeToLiveSpecification for DynamoDB using CloudFormation

I've deployed DynamoDB table using CloudFormation like this:

  exampleTable:
    Type: AWS::DynamoDB::Table
    Properties:
      BillingMode: PAY_PER_REQUEST
      KeySchema:
        - AttributeName: id
          KeyType: HASH
        - AttributeName: prop
          KeyType: RANGE
      TimeToLiveSpecification:
        AttributeName: foo
        Enabled: true

Changeing TTL attribute to bar successfully deployed, but changes does not reflect to dashboard.

https://docs.amazonaws.cn/en_us/amazondynamodb/latest/developerguide/time-to-live-ttl-before-you-start.html#time-to-live-ttl-before-you-start-notes says

You cannot reconfigure TTL to look for a different attribute. You must disable TTL, and then reenable TTL with the new attribute going forward.

Do I need to deploy 2 times even when using CloudFormation? (once for disabling TTL and once for enabling TTL with new attribute name)

Yes. The fact that you have to disable it first is explicitly stated in CloudFormation docs for AttributeName:

To update this property, you must first disable TTL then enable TTL with the new attribute name.
