Can I get grafts removed?

A revision can definitely be performed to remove grafts and change the shape to something more fitting with what you are going for.
That said, important to make clear that most well-done noses should be stiff immediately after surgery. I don't know when your surgery date was, but your nose should continue to soften with time.
However, if you want to change the shape (deproject and shorten), that probably won't change too much, and a revision is needed to help with that. Hope this is helpful!

The revision operation you're describing is what a lot of complicated revisions are. But in order to know for sure, you have to sit with and be examined by a surgeon who has the skill to perform an operation like that, so he can tell you what's possible. Photos help, too, because in general, the more you want to change the *appearance* of the nose, the more likely it is that an operation can be designed to address your concerns.

Grafts can be removed or adjusted. But, where is the picture? What does it look like? When was the revision? Things also soften over time.
