Answer 1

Try this, you can extend using preference

Add di.xml in the below folder

app/code/Vendor/ModuleName/etc/di.xml

then add the below code to it

<?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="Magento\Framework\Config\SchemaLocator" type="Vendor\ModuleName\Config\SchemaLocator" />
</config>

then add SchemaLocator.php in the below path

app/code/Vendor/ModuleName/Config/SchemaLocator.php

then add the below code to it

<?php
namespace Vendor\ModuleName\Config;
use Magento\Framework\Module\Dir;

class SchemaLocator extends \Magento\Framework\Config\SchemaLocator implements \Magento\Framework\Config\SchemaLocatorInterface
{
   protected $schema = null;
   /**
 * @param \Magento\Framework\Module\Dir\Reader $moduleReader
 */
public function getSchema()
{
    $result = sprintf(realpath(__DIR__ . '/../etc/view.xsd'));
    return $result;
}

/**
 * {@inheritdoc}
 */
public function getPerFileSchema()
{
    return $this->_schema;
}
}

the above code will change the path of view.xsd to your custom module from core.

Finally, add the view.xsd in the below path

app/code/Vendor/ModuleName/etc/view.xsd

then you can add you changes there.

NOTE : This is working example in M2.3 and in previous version used plugin instead of preference
