Hi,

you can use the acf/prepare_field filter for that.
https://www.advancedcustomfields.com/resources/acf-prepare_field/

In the function, you first check if the value is null. Only a newly create post will have null, if it’s a saved post that has no value, it’s an empty string.

<?php

add_filter('acf/prepare_field/type=image', 'acf_use_default_image');

function acf_use_default_image($field) {
    if ($field['value'] === null) {
        $field['value'] = 5; // attachment id
    }

    return $field;
}

Cheers 🤗
