Integration with ACF?

I have site I am building for a client. His clients can create jobs using Front End Forms by Dynamiapps. All of that is working as intended except we need a way to allow file uploads to our Wasabi storage that integrates with the form. Is there any way to tie your plugin into ACF as a new field type? This is literally the last piece of the puzzle for this site.

Second question would be, is it possible to have the files be renamed using the $post_id, $filename, $file_extension? Really just wanting to prepend the filename with the post id on upload. Thanks!
