Hi @stinkykong
There is no official GF integration for ACF however it’s possible someone else has coded something.
There is for example an addon which allows you to select a GF form with an ACF field.

Otherwise I recommend you do some google search for other add ons out there or check the WP repo: https://wordpress.org/plugins/search.php?q=Advanced+Custom+Fields
