How to create New content type? I’m using the plugin Custom Post Type UI, but a lot of trash. For example, the title, how to automatically generate a name from the ACF fields? Or it will be empty? How do I turn off the preview? How can I make sure that I have only the form and fields created in ACF?
When setting up a custom post type you can turn of support for most things. This is part of the CPTUI plugin.
Generating the title from an ACF field can be done using an acf/save_post filter https://www.advancedcustomfields.com/resources/acf-save_post/ I’m sure that are many answers to this in the topics of this forum, as well as other filters that can be used. Basically you create your filter and in the filter you use wp_update_post() https://codex.wordpress.org/Function_Reference/wp_update_post to set the title.
Doing something like turning of preview is another question entirely and is not something that ACF will do for you. This might help you in the right direction http://wordpress.stackexchange.com/questions/121640/hide-view-and-preview-from-custom-post-types
