How to login a user with an E-mail to magento2 site without triggering event 'customer_login'.
Actually, I am able to login with email using customer session but the customer session also triggers the 'customer_login' events. I don't want to use a trigger.

    $customer = $this->_customer->loadByEmail("[email protected]"); 
    $this->_customerSession->setCustomerAsLoggedIn($customer);
