I used force source 
І downloaded the building system and searched where and how to turn on the pci bus ... and i found and turned on.
the patch is very simple
diff --git a/target/linux/ramips/dts/mt7628an.dtsi b/target/linux/ramips/dts/mt7628an.dtsi

and that's what happened, the mt7612e chip was found and started working, I'm actually writing this message by connecting through it.

But there is one problem: this chip works at a very low power - 1 dBm (1mW), the router is at a distance of 3m from me and the wifi signal is a little more than zero, although it works stably, I can watch videos from YouTube, the speed is enough.
