PPTP VPN with EAP authentication

Is it possible to configure PPTP Server on CCR1009 to use EAP authentication with Radius Server on Windows 2012? VPN runs with MS-CHAPv2 without problems, but I want to use smart cards to authenticate users, as it works with Windows RRAS.

As far I as know, this is not possible, but it would be great to have that implemented in order to get rid of the MS-Chap v2 Authentication method, which can be cracked within 24 hours.
