I believe it’s possible, but you need an advanced knowledge of PHP to do it. Instead of multiplying acf_form(), I think you can use a repeater field so you can add and remove the number of posts you want.
After that, you need to use the acf/save_post hook and loop through the posted repeater data using the $_POST[‘acf’] variable then save it using the wp_insert_post() function.
I hope this makes sense. Thanks!
