Google’s John Mueller answered on the visibility of the URL with respect to the search result by country. Mueller said there is no way to limit the visibility, if a user wants a specific URL in Google UK and don’t want in Google Ireland, there is no way to hide the URL.

Pedro Teixeira asked a question,

“A page with English content that is only available and appropriate for searches/users in the Netherlands (google.nl) still shows up for UK searches (google.co.uk). Is there a way to inform Google that these specific English URLs are exclusive to a country and no alternate URLs exist?”

John Mueller answered on this,

“There is no mechanism to limit the visibility of a URL in the search results by country, so the best you could do is to try to catch it on your end. Eg, I’ve seen sites show a banner (unfortunately not available in X), some also refer to partners in other countries.”
