Does OpenDistro have it's own repository-s3 plugin

We are looking to backup our indexes to s3 and I was wondering if OpenDistro has it’s own S3 plugin or if it relies on the one from Elasticsearch?

Only the credential provider in that plugin is very limited; for instance it does not appear to use any of the standard providers; I am particularly interested in the Web Token credential provider so access can be granted via a service account and OIDC!
