Yes, Clair Obscur: Expedition 33 has multiple endings. Players have the ability to trigger two different endings depending on how they handle key events near the end of the game. At this time, there are no secret or additional endings that can be triggered, even with the use of specific items or the completion of side quests.

One of the first side quests you'll stumble upon in Clair Obscur: Expedition 33 asks you to find all of Sastro's lost Gestrals. There are nine of them in total, and with how big the overworld is in this turn-based RPG, it can be a nightmare to track them all down.
