I want to Remove slug

As far as I’ve ever seen, there’s never been a great, foolproof way for this via the register_post_type() function, which is what we collect arguments for with our UI.

Best I can offer is the following, without doing more googling around for the topic:

https://wordpress.stackexchange.com/questions/203951/remove-slug-from-custom-post-type-post-urls
https://wordpress.org/plugins/remove-slug-from-custom-post-type/

The first link is pretty new and talks about how to go about it in 2017. The latter is an admittedly older plugin, not touched in 5 years, but it’s worth trying in my mind.

We have fields available for all the parts mentioned in the stackexchange first reply, regarding 'rewrite' => array( 'slug' => false, 'with_front' => false ),

Any parts with pre_get_posts and post_type_link filtering, we don’t have UI elements for. If you need to go this route, then it’s going to be a custom solution to handle.
