I’m trying to make it so my custom taxonomy terms don’t have archive pages. I achieved something similar for a custom post type using “publicly_queryable’ => false”. I tried this from the docs inside the register_taxonomy function:
'public' => false,
'rewrite' => false,
Which works.. but it also removes the ability to view the taxonomy from anywhere in the dashboard.
If you set public to false, this taxonomy will get hidden in all places.
So if you want it to be visible in wp-admin, you’ll have to also set show_ui to true – it will show the admin interface to manage this taxonomy.
You can see the full list of params here:

And here is a generator, that may be a nicer way to create code for registering taxonomies/posts:
