Hmm, not a bad idea to play with. That may create an issue as the form processor needs that goodies in there.
Here’s what I’m currently using as my solution but I’d love to hear if it’s faulty.
Basically I made a copy of acf_form_head() and removed the part that tries to update/create posts. Just put this before get_header() instead of acf_form_head()
