Question on creating an archive template?

This question might be a little out of scope for this support, but here goes..

So, for a variety of reasons I'd rather hide the loop of some Custom Taxonomy I have in my GeneratePress install.

My question is twofold...

1. My Custom Taxonomy is called "countries" so am I correct in thinking that I can create a template called category-countries/php, and place that in a child folder and copy/paste over the category.php code minus the loop bit and I'm all good?

2. What would you advise to do to remove the archive post loop?

I still need the URL of the Custom Taxonomy and will place content on that page.

Hope that makes sense and any help/advice is greatly appreciated.

Thanks!
