Hi @homax
It is possible, because ACF can save postmeta or the connection from post to term.
All you need to do is use the native WP_Query class to do any querying you wish.
There are plenty of docs on this site as to how to query custom field values.
How to query for taxonomy data? This is not ACF territory, that is why I recommend google.
Please remember ACF is only a UI interface for the native WP functionality. You are not restricted to the ACF API at all!
Thanks
