vpn settings pages here:

, .

actually need add button system vpn settings clicking on custom dialog vpn specific settings shown.

here starting point @shoe rat proposed, using java reflection:

i didn't have time test it, surely give starting point. i'm not sure root access needed accessing hidden api. please bare in mind might throw securityexceptions or illegalaccessexception.
