Is it possible to limit shipping carrier by country?

_shippingService.GetShippingOptions() accepts a "allowedShippingRateComputationMethodSystemName" parameter, so since you're already overriding PrepareShippingMethodModel() you could only load the relevant plugin per country by passing the system name:

public virtual GetShippingOptionResponse GetShippingOptions(IList<ShoppingCartItem> cart, Address shippingAddress, Customer customer = null, string allowedShippingRateComputationMethodSystemName = "Shipping.UPS", int storeId = 0)
