yesssssssss but I’m out of home in this moment. I cannot past any code. in 2 words. you have to clone the standard divi module in your child theme and edit the id field that populates the divi gallery with the acf field. but you have to enable this custom module only in the cpt that you are interested to apply this kind of feature elsewhere this will breack the divi gallery in your entire website
