No.

The Eternal Edition is a package consisting of the D:OS 2 Divine Edition, D:OS Enhanced Edition (not Classic) with its Collector's Edition extra content (soundtrack, design documents, art pack) and the earlier three games Divine Divinity, Beyond Divinity and Divinity 2 Developer's Cut.

The D:OS 2 Divine Edition is the Definitive Edition of the game, plus the 'Divine Ascension' DLC content (soundtrack, a pdf map, art and lore books).

That is the full list of Larian RPGs (though a typo in 5; the game itself is the Definitive Edition).

There is also Divinity: Dragon Commander, a diesel punk strategy game with turn based moves on the world map, RPG elements / story at the base between turns and real time combat skirmishes (or combat can be auto resolved) where you control your units and/or enter combat as a dragon (with a jet pack).

This evolved out of looking at dragon combat after Divinity 2 was finished, and noticing that a higher speed made air combat more fun (flying was good, but combat not very compelling). And of course the best way to give a dragon a speed boost is with a jet pack, so that is how the diesel punk aesthetic started.
