Spaying will definitely help. It will take some time for her hormones to dissipate, and she could go through a post-spay craze where her body is adjusting. But overall it will make her much better, as the majority of it is probably hormonal.

As a side note, females should be spayed anyways to greatly reduce their risks of reproductive cancers.

Spaying your little love should help!
There is always the chance that spaying will not fully cover all behaviors, meaning she could possibly be an aggressive rabbit by nature as she has matured. However, it should take a lot of the edge off, just as our friend above has pointed out.
With my experience, my bunny Bindi was very aggressive at times with me as well while she was not spayed. I got her spayed after waiting a full year (mainly financial reasons), and I wish I would have gotten it done sooner than that. But now she’ll be two in April and I love how getting her spayed has calmed her down. She’s still pretty independent, and does box me at times if I approach her a certain way, but that is the kind of rabbit she is (also I believe it was how she was handled when she was small and impressionable).
But yes, you should get her spayed and spayed soon! Getting her spayed will not only be great for toning down her aggression, but also expanding her life. Female rabbits have almost a 75% chance of developing reproductive tract cancers.
Also, this is great for litter box habbits as well. ?
