Hi Devin, the switch does support port security which can allow certain MAC address to use a particular port or limit the number of MAC addresses connecting to a port. This switch does not have a dynamic ARP inspection.

Unfortunately I cannot give a specific example to the sg200-8 model since I don't have one on hand. However, here are a couple documents I created for the bigger brother, the SX300 series. Hopefully it is comparably close enough for you to get what you want if port security is what you're looking for.
