Hello Colin,
Thank you for interesting in our EShop Shopping Cart extension. Regarding your question: Yes, default EShop Free shipping plugin allows you to setup Free Delivery option for a specific Geo Zone as you want.
Please read the documentation about it here:

If you have any more questions, don't hesitate to let me know.
Sincerely, Giang
