Hi @PerS
I took a look and in english, the option you have circled is called ‘slug’. This refers to the metabox and ‘Show on screen’ option of ‘slug’.
This is different to the Permalink UI you have highlighted.
In short, ACF does not yet contain the functionality to hide this element from the page. I’ll add this to the to-do and add in the ‘Permalink’ hide on screen setting.
Thanks
