Does this plugin support tenants?

We have filters for dynamically adjusting settings keys such as bucket and object-prefix which may be useful for multi-tenant scenarios.

We have a guide for their use in the context of a multisite that should help.

We also have an as3cf_object_meta filter that can be used to adjust the destination bucket, key and various other values that would be used when using putObject() (or its equivalent) to offload an item:

That would be the filter to use if information related to the Media Library item is needed to determine the destination, e.g. user that uploaded it.
