What do I need to set in a D8 view, to have one view per taxonomy vocabulary without any contrib module?

Drupal 8 already uses the (now-builtin) Views for listing pages of content belonging to a certain taxonomy term.
That's a single view for all taxonomy terms:
You can edit the view and make necessary changes you need http://example.com/admin/structure/views/view/taxonomy_term
I don't know why anyone would have a "without a contrib module" requirement.
You can either do this with Page Manager, or you can write a custom module that alters the route and then dynamically calls a different view. Drupal 8 doesn't provide a feature to do this without additional modules/code
