Bitrix non-blocking session in memcached?!?

Question

1C-Bitrix

I found the Bitrix setting to store the session in memcached:

'session' => [
        'value' => [
            'mode' => 'default',
            'handlers' => [
                'general' => [
                    'type' => 'memcache',   
    		    'port' => '11211',
    		    'host' => '127.0.0.1',
                ],           
            ],

        ]                   
    ]

But this option is not quite suitable, since I need a non-blocking mode. Please tell me if there is such a setting in .settings.php?!??
