I agree with the comment.
The display of this is set by the user role and their access to the site.
You can alter the permission to edit field groups by modifying the ACF capability setting https://www.advancedcustomfields.com/resources/acf-settings/
Unfortunately, if your user is an admin this won’t do you much good.
You can also hide the admin https://www.advancedcustomfields.com/resources/how-to-hide-acf-menu-from-clients/
