Problems config HAP AC as Home Internet Router PPPOE

Greetings.
I live in Brazil and I´ve a Hap Ac RB962UiGS-5HacTsHNT-US and I am not getting to config to use with my home router and wireless.
The menu PPP is not showing in the menu lateral bar. A nothing I did could set a Pppoe (I user Internet Fiber provider)

What can I did wrong? It should be easy.

Look on system.. Packages if you have ppp enabled of it is at all there.
