Blocking a country from visiting a website?

I’m running a Shopify based store and of late have noticed getting hundreds if not thousands of visits from presumably bots. Usually they’re from Ashburn but this week they’ve all been coming from Falkenstein (Germany), already today I’ve had 1,300 hit my store with currently 37 active. It’s messing with my tracking of SEO and conversion, is they’re anyway to block said countries? We only operate in the UK so it wouldn’t affect our business.
