You can easily override the file as this following steps

Step 1: you need to create di.xml file in your own Module. Path: [VendorName]\[ModuleName]\etc\

Step 2: Write this following code in your di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Pepperjam\Network\Model\Beacon\Itemized" type="[VendorName]\[ModuleName]\Model\Beacon\Itemized"/>
</config>
