How do you remove marketplaces you don’t want to sell to?

Hello,

I have a UK based FBM individual seller account and I only want to sell in the UK. I would like to remove every other country from my marketplace list. I don’t want to ship anywhere other than the UK. How do I do this? I’ve seen an option to put my shop on vacation mode for other countries but I want to actually never sell to any other country.

Thanks.
