Pretty simple solution:

add_filter( 'acf/validate_post_id', 'skip_acf_polylang_options', 10, 2 );
$my_field = get_field( 'my_field', 'options' );
remove_filter( 'acf/validate_post_id', 'skip_acf_polylang_options' );

And the actual filter function:

function skip_acf_polylang_options( $future_post_id, $original_post_id ) {
	return $original_post_id;
}

This way you can skip overridden options name…
