Hide meta IF it's 'something' and 'somethingelse' in Foreach loop else display all

Code below is great to display ALL the meta of an item in the order - How do I hide certain meta from displaying? eg. display all except if meta key is 'something' and 'somethingelse'

    <?php
foreach ( $order->get_items() as $item_id => $item ) {
    $item_meta_data = $order_item_product->get_meta_data();
    echo $product_name = $order_item_product->get_name();
    echo '<br>';
foreach( $item_meta_data as $meta_data ) {
        $meta_data_as_array = $meta_data->get_data();
        echo $meta_data_as_array['key'].': '.$meta_data_as_array['value'].'<br>';   
        
       
}

}
?>
