Can a single state be shown in maps instead of the whole US?

Unfortunately I do not believe so, but it is in their backlog to do: https://dojo.domo.com/t5/Ideas-Exchange/US-State-Level-Map-Cards/idi-p/11627

The closest thing that I can think - If you use Latitude and Longitude with the LAT/LONG Map - it will automatically zoom in based on the data used, but it won't be just a state.
