Answer 1

Check the assigned block to render the order items defined in layout file vendor\magento\module-sales\view\adminhtml\layout\sales_order_view.xml

<block class="Magento\Sales\Block\Adminhtml\Order\View\Items" name="order_items" template="Magento_Sales::order/view/items.phtml">

Block method \Magento\Sales\Block\Adminhtml\Order\View\Items::getItemsCollection() responsible for serving order item data to this page template.

You can get an idea to filter order item data on that collection in order model:

\Magento\Sales\Model\Sales::getItemsCollection($filterByTypes = [], $nonChildrenOnly = false);
