Armbian Stretch is not using Predictable Network Interface Names. Why?

First of all, sorry if I'm asking something really obvious, but I'm new in Linux. 

Hi! 

I just have a new fresh install of Armbian Stretch on my Cubox, and I just realized that Armbian isn't using the Predictable Network Interface Names but the old one.

I can't even find the /etc/dhcpcd.conf file

Is this correct or I've done something wrong?
