I am struggling with the same “issue”, and I tried John Huebner’s example, but the function to generate the id doesn’t work (the value of the variable is null when echoed).

add_filter('acf/prepare_field/key=field_62440b6868c96', 'is_readonly');

function is_readonly($card_group_id) {
    $card_group_id['readonly'] = true;
    return $card_group_id;
}

add_action('acf/save_post',  'generate_cardgroup_id');

$post_id = get_the_ID();

function generate_cardgroup_id($post_id){
    if (!$rows['card_group_id']){
        $rows['card_group_id'] = uniqid($more_entropy);
    }
    $rows['card_group_id'] = 1234;
}

Please could someone have a look? I’m really frustrated 🙁
