No. The fields need to exist on the site, in the db, using acf json files or created using php. The best you can do is to hide the admin https://www.advancedcustomfields.com/resources/how-to-hide-acf-menu-from-clients/
Well, I take that back. If you built the theme to use the associated get_meta() or get_option() WP functions rather than than ACF functions for getting field data then you could potentially do this. But basically you’d have to rebuild all of what ACF does to get the values for you.
