Reverse-tethering to an iPhone (jailbroken if it helps)

Hello, I am getting a MT7628AN router (Will use OpenWRT of course) soon and I've been wondering if I can Reverse-Tether the router's internet connection to an iPhone (iOS 14.4.2 Jailbroken)

Yes I know I can use WiFi but please I just want to know if it can be done or not

I saw this thread/tutorial

Would I be able to reproduce the last 4 steps in OpenWRT?
