I want to override model in the Magento 2

Question

I want to override the Magento\Catalog\Model\Layer\Category\FilterableAttributeList model file. I have created the module. This is my di.xml file.

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="Magento\Catalog\Model\Layer\Category\FilterableAttributeList" type="Pos\AdvancedLayeredNavigation\Model\Layer\Category\FilterableAttributeList" />
</config>

This is my model file,

<?php
namespace Pos\AdvancedLayeredNavigation\Model\Layer\Category;
class FilterableAttributeList extends Magento\Catalog\Model\Layer\Category\FilterableAttributeList
{
 public function getList()
    {
     /** @var $collection \Magento\Catalog\Model\ResourceModel\Product\Attribute\Collection */
        $collection = $this->collectionFactory->create();
        $collection->setItemObjectClass(\Magento\Catalog\Model\ResourceModel\Eav\Attribute::class)
            ->addStoreLabel($this->storeManager->getStore()->getId())
            ->setOrder('position', 'DESC');
        $collection = $this->_prepareAttributeCollection($collection);
        $collection->load();

        return $collection;
    }
}

Can you guys help me!!!! Is there any way to overwrite this file?
