When considering the Cayley graph of $\mathbb{Z}_3 \times \mathbb{Z}_3$ with respect to the generating set $S=\{(0,1),(1,0)\}$, as shown in Figure (1) below, can I regard the graph in Figure (2) as one of its automorphisms?

If you mean to ask if your second graph represents the Cayley graph of your group with respect to the generating set $\{(0,1),(1,1)\}$ corresponding to the automorphism of $\mathbb{Z}/3\mathbb{Z}\times\mathbb{Z}/3\mathbb{Z}$ given by
$$(0,1)\mapsto (0,1) \quad(1,0)\mapsto (1,1)$$
then yes it does.
