Edit /etc/config/network in squashfs before image

Is there a location for the /etc/config/network file where when I do a make, it puts that file in squashfs volume. ie: I want to edit that network file before it goes into squashfs, then to img file where I flash it.

I found similar to https://github.com/openwrt/openwrt/blob/master/target/linux/at91/base-files/etc/config/network

but I want it for my ath79 device.
