Yes, you can set it up easily.
E.g. you need people from Antigua and Barbuda watch your live broadcast and hide it from all other countries. To make this, just add the country to allow list, then scroll down to "Re-publishing protection", check all protocols and enter any non-zero length password. So if someone comes from Antigua, he (or she) will pass the check for allow list and will be allowed to watch the stream. Any guy from, say, Jamaica, will pass the check for country (as Jamaica is neither in allow or deny list) but will fail the check for re-publishing protection.
Need several countries to be allowed? Just add them to allow list.
