How to Block International Orders and Restrict Sales to the UK Only?

Hello, I am a UK-based seller on Amazon, and I’m currently facing an issue where I’m receiving orders from countries like Italy, Spain, and France, even though my focus is solely on selling within the UK. This is causing unexpected complications, including higher FBA fees. I’d like to know if there’s a way to block international orders or restrict my store visibility to the UK only. Has anyone else experienced this, and can you guide me on the best steps to resolve it? Any insights would be greatly appreciated!
