Answer 1

It's very simple, you just need to add below code in your di.xml file here in your custom module

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

Content for this file is..

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\Sales\Model\ResourceModel\Report\Bestsellers\Collection" type="Vendor\Module\Model\ResourceModel\Report\Bestsellers\Collection" />
</config>

Now create Block file here

app/code/Vendor/Module/Model/ResourceModel/Report/Bestsellers/Collection.php

Content for this file is..

<?php

namespace Vendor\Module\Model\ResourceModel\Report\Bestsellers;

class Collection extends \Magento\Sales\Model\ResourceModel\Report\Bestsellers\Collection
{
    protected function _construct()
    {
        parent::_construct();
        $this->_ratingLimit = 15; //change Default Limit Number here as you want
    }
}

Just set Default Limit in __construct() and run below commands

php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento cache:clean
php bin/magento cache:flush

Hope this will help you!

You need to override \Magento\Sales\Model\ResourceModel\Report\Bestsellers\Collection class in your custom module and set $_ratingLimit as per your requirement. Please check the below code for your reference.

Vendor\Module\Model\ResourceModel\Report\Bestsellers\Collection.php

<?php
namespace Vendor\Module\Model\ResourceModel\Report\Bestsellers;

class Collection extends \Magento\Sales\Model\ResourceModel\Report\Bestsellers\Collection {

    /**
     * Rating limit
     *
     * @var int
     */
    protected $_ratingLimit = 500;

}

Vendor\Modul\etc\adminhtml\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="Magento\Sales\Model\ResourceModel\Report\Bestsellers\Collection" type="Vendor\Module\Model\ResourceModel\Report\Bestsellers\Collection" />
</config>

Edit:

After adding these files in your custom module, please run below commands:

php bin/magento s:up
php bin/magento s:d:c
php bin/magento s:s:d
php bin/magento c:f

Hope it helps!!!
