ACF has it’s own function and hooks
$errors = apply_filters( "acf/upload_prefilter/type={$field['type']}", $errors, $file, $field );
$errors = apply_filters( "acf/upload_prefilter/name={$field['_name']}", $errors, $file, $field );
$errors = apply_filters( "acf/upload_prefilter/key={$field['key']}", $errors, $file, $field );
$errors = apply_filters( 'acf/upload_prefilter', $errors, $file, $field );
Same as the wp hook but also passes the $field.
