you can achieve this by adding your template file to sales_order_view.xml ,
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="admin-2columns-left" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
<referenceBlock name="order_info">
<block class="Learning\RewriteSales\Block\Adminhtml\Order\View\Custom" name="sales_order_view_custom" template="order/view/custom.phtml" />
</referenceBlock>
</body>
</page>
and in your template file you can get the relevant information . for this you have to create
1.one block 'Learning\RewriteSales\Block\Adminhtml\Order\View\Custom'
2.one template 'order/view/custom.phtml'
3.and the changes to sales_order_view.xml as mentioned above ,
