Is it possible in Wan 2.1 to repeatedly generate the same video and change only small details using

Is it possible in Wan 2.1 to repeatedly generate the same video and change only small details using prompts? For example, let's say I have a scene and I only don't like some object in the background, which I want to prompt differently. Or the resolution. Everything else is perfect and should not change. Or is the output always random?

And is it possible to fine-tune Wan 2.1?
