How to override or disable core Plugins in Magento2?

Question

I am building a marketplace using Magento2. For that reason I need to be able to load the order of the customer using the vendor's customer credentials.

The problem with this is that Magento2 uses a Plugin to verify that only the Customer of this order (or an Admin) can load the order.

In this case I need to either override the Plugin as a whole, or override the protected method isAllowed(). What can I do without modifying the core?

Magento\Sales\Model\ResourceModel\Order\Plugin\Authorization Looks like this:

use Magento\Authorization\Model\UserContextInterface;
use Magento\Framework\Exception\NoSuchEntityException;
class Authorization
{
    /**
     * @var UserContextInterface
     */
    protected $userContext;

    /**
     * @param UserContextInterface $userContext
     */
    public function __construct(
        \Magento\Authorization\Model\UserContextInterface $userContext
    ) {
        $this->userContext = $userContext;
    }

    /**
     * Checks if order is allowed
     *
     * @param \Magento\Sales\Model\ResourceModel\Order $subject
     * @param callable $proceed
     * @param \Magento\Framework\Model\AbstractModel $order
     * @param mixed $value
     * @param null|string $field
     * @return \Magento\Sales\Model\Order
     * @throws NoSuchEntityException
     * @SuppressWarnings(PHPMD.UnusedFormalParameter)
     */
    public function aroundLoad(
        \Magento\Sales\Model\ResourceModel\Order $subject,
        \Closure $proceed,
        \Magento\Framework\Model\AbstractModel $order,
        $value,
        $field = null
    ) {
        $result = $proceed($order, $value, $field);
        if (!$this->isAllowed($order)) {
            throw NoSuchEntityException::singleField('orderId', $order->getId());
        }
        return $result;
    }

    /**
     * Checks if order is allowed for current customer
     *
     * @param \Magento\Sales\Model\Order $order
     * @return bool
     */
    protected function isAllowed(\Magento\Sales\Model\Order $order)
    {
        return $this->userContext->getUserType() == UserContextInterface::USER_TYPE_CUSTOMER
            ? $order->getCustomerId() == $this->userContext->getUserId()
            : true;
    }
}

You can disable plugin by name. In your case it authorization.

<type name="Magento\Sales\Model\ResourceModel\Order\Plugin\Authorization">
    <plugin name="authorization" disabled="true" />
    <plugin name="vendor_name_authorization" type="Vendor\Name\Model\ResourceModel\Plugin\Sales\Order\Authorization" sortOrder="1" />
</type>

Then you should create own class, which will extend the magento plugin class. In own class you can overwrite protected method.

You can do it without delete and recreate plugin:

<type name="Magento\Sales\Model\ResourceModel\Order\Plugin\Authorization">
    <plugin name="authorization" type="Vendor\Name\Model\ResourceModel\Plugin\Sales\Order\Authorization" sortOrder="1" />
</type>

Sample code of your plugin class:

namespace Vendor\Name\Model\ResourceModel\Plugin\Sales\Order;
class Authorization extends \Magento\Sales\Model\ResourceModel\Order\Plugin\Authorization
{
    protected function isAllowed(\Magento\Sales\Model\Order $order)
    {
            ///You code here
    }
}

If you use sergei.sss 1st solution, you will get the error of duplicate Magento\Sales\Model\ResourceModel\Order\Plugin\Authorization
The correct way to do that is:

<type name="Magento\Sales\Model\ResourceModel\Order\Plugin\Authorization">
    <plugin name="authorization" disabled="true" />
    <plugin name="vendor_name_authorization" type="Vendor\Name\Model\ResourceModel\Plugin\Sales\Order\Authorization" sortOrder="1" />
</type>
