Hey,
If you can configure the s3 endpoint url on Dremio then it should work over lakeFS. The repo becomes the bucket name, the branch the initial path prefix, and data on lakeFS is accessible via the s3 protocol. That might be a lot like configuring to work with a minio setup.
So TBH I don't know of any current connection made, but I'll ask around once people here head to the office (around 7-8 hours).
