Hi spottedinely,
WordPress itself supports the delivery of Atom-format feeds and it’s possible to view content created by The Events Calendar/Events Calendar PRO in such a feed:
example.com/feed/atom/?post_type=tribe_events
If you craft a URL such as the above, obviously changing the domain to match your own, you should find that events are delivered in Atom format.
Do note however that, unlike RSS format feeds, no special work is done to change properties of event posts and so they will be listed according to publication date rather than event date.
Does that help?
