Something like

resources:
  something:
    type: aws:s3:Bucket
    properties:
      ...
    options:
      version: 5.6.0

@tall-librarian-49374 so I tested both approaches: 1. adding a version tag via options works. Although it's kinda inconvenient because variable or configuration expansion isn't possible 2. Seems it's not possible to create an explicit provider instance via YAML. In any case, I don't see an area where you could define a provider. If this is done in the resources section, an error will occur, of course. A provider is not a resource.

@tall-librarian-49374 sorry for bothering you again 😏 I disabled default providers and I'm happy with normal resources because, as you described, they work flawlessly with explicit provider instances. But I get an error about an

Fn::Invoke

that calls

getClientConfig

of the Azure Classic provider, stating that default providers are disabled. I don't see any possibility to specify the provider instance with an

Invoke
