Hello!

So I mostly use Unity for my game development, and I've been wanting to use Godot for this jam. 

However, I did use Godot for a bit a couple of months ago for the 2D tutorial. However, I stopped using the engine after that, so I would still very much consider myself a beginner in the engine.

Would I still be able to use Godot for the jam?

Thanks.

i mean, you’re not breaking any rules, since there aren’t really any rules stating you must use something you’ve never used before, so i would say go ahead

The jam is thematically about switching engines to greener pastures but is more specifically about playing with something new-to-you. Finishing a tutorial is very different from going through the motions of creating something from whole cloth so go for it. It's a month long jam to give time for learning, so going through one tutorial isn't going to give you an unfair advantage.
