Yes, I can confirm to you that Denodo provides users with different connectors and components that expand the possibilities of the Denodo Platform. These components are available in the "Denodo Support Site" and for accessing to this site you need a support user. The "Denodo Distributed File System Custom Wrapper" component allows users to access Amazon S3 files, among others (HDFS, Azure Data Lake Storage, Google Cloud Storage...).
As you are using a free trial, a denodo representative will reach you to get a better understanding of your needs.
Hope this helps!
