I was looking for ways to visualize model that we fine tuned in lesson one.

Is there any way to visualize what layers are final.

Is there any use and/or way to control how many final layers will be retrained?

You can check class Learner() in fastai/learner.py:

def freeze_to(self, n):
    c=self.children
    for l in c:     set_trainable(l, False)
    for l in c[n:]: set_trainable(l, True)
