I can give you a basic example

add_filter('acf/prepare_field/key=field_123abc456

, ‘maybe_set_readonly’);
function maybe_set_readonly($field) {

// check post type to see if it’s a new post
global $post
$new_post = true
if (get_post_type($post->ID)) != ‘auto-draft’) {
// this is not a new post
$new_post = false;
}

// check current user role
// I really don’t know off the top of my head how to check this

// if conditions are not met to allow editing
// set field to readonly
if (your conditions here) {
$field[‘readonly’] = 1;
}
return $field;
}
