HTTPs traffic block

Hi guys,

We are using Lede + WifiDog plugin for simple authentification method, preventing user to connect to Internet.
In order to login, user need to use his social profile or mobile number. HTTP traffic we blocked successfully and user can't connect until he sign in, but HTTPs traffic we cannot block because user need to sign in through Facebook account.

Here is my question.
How it is possible block HTTP and HTTPs traffic and allow user to sign in using Facebook account. I know it is possible to do it using radius server, but we are using combo Lede + WiFidog.
