How do I tell Rector to not apply any changes except those related to PHP compatibility?

As title states, I’m only interested in issues that can affect PHP compatibility, but it keeps changing array() into [] etc. Any tips?

My rector.php config so far:

return static function (RectorConfig $rectorConfig): void {
    $rectorConfig->rules([]);
    $rectorConfig->sets([LevelSetList::UP_TO_PHP_82]);
    $rectorConfig->paths([
        // my paths
    ]);
};
