What’s the name of the custom post type yearly archive template?

CPT’s don’t have date archives, those are a post specific feature.

Having said that, nothing prevents you building a custom bespoke date archive for a CPT. Just don’t expect WordPress core to do it for you, it would be a 100% custom job, you’d have to load your own date templates, modify the query, add the rewrite rules, and construct the URLs yourself.

The closest you can get out of the box, is visiting a CPT’s archive, and appending query args to the URL, e.g. example.com/yourcpt?year=2022, but this will give you the same archive as that URL but with the additional filtering to 2022. Note that this only works with standard archives, it will not work if you replace the main query, rely on page templates to recreate archives, or use a page builder. It also won’t be considered a date archive by WordPress functions and APIs
