You could have to different field groups, that that’s shown on the user side and one that’s shown on the admin site. Then using an acf/save_post filter copy the values to the admin field group and delete things from the user field group if you need to. I created a custom location rule a while back that let’s you include field groups base on whether it’s on an admin or front end page. https://github.com/Hube2/acf-filters-and-functions/blob/master/is_admin-acf-location-rule.php
