There are a couple of choices.
1) Add an acf/format_value filter https://www.advancedcustomfields.com/resources/acf-format_value/
// filter with high priority to run after ACF add_filter('acf/format_value/type=file', 'my_change_to_cdn', 20, 3);
See the filter documentation. In the filter you can replace the domain name of your site with the domain name of the cdn.
2) Get just the attachment ID and then do all the work of generating the URL yourself using standard WP functions and other code.
// 3rd parameter = false returns unformulated value // which is the ID value for images and files $attch_id = get_field('file_field_name', false, false);

ACF wouldn’t be so widely used in WordPress if it didn’t have some pretty amazing capabilities. In this article, we look at a few of the features we’ll discuss during “7 things you didn’t know you could do with ACF” at #WPEDecode later this month. https://t.co/5lnsTxp81j pic.twitter.com/Yf0ThPG1QG— Advanced Custom Fields (@wp_acf) March 16, 2023
