If you need specific queries to be strongly consistent, DAX will honor that parameter if you pass it in the API call.

To perform a strongly consistent GetItem, BatchGetItem, Query, or Scan request, you set the ConsistentRead parameter to true. DAX passes strongly consistent read requests to DynamoDB.

Source https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DAX.consistency.html#DAX.consistency.strongly-consistent-reads

The other possibility is to use 2 clients. The DAX one for queries that you want cached and the dynamodb one for queries that you need to bypass the cache. Since DAX implements the sam API as dynamodb, it shouldn’t be too hard to implement.
