If you are referring to animations similar to GSAP then no. However, you can create for each node in your scene graph a script that transforms object in arbitrary ways (and thus animate objects).
I suggest you create a script on the top-most glTF node and then query your glyph objects via Object3D.getObjectByName(). You should then be able to implement any object transformation you like.
I think this thread and the respective live example should help: Three.js + Gsap ScrollTrigger
But notice that it is not possible to include third-party scripts into the editor. If you need GSAP for animations, you have to copy the editor source into your project and implement a custom enhancement.
