Show mobile ip while connected to wifi?

I have phone with sim what has internet, but it's very limited. Can I connect and use pc's unlimited wifi in way that it shows phone's sim IP not pc's? If I connect wifi it also changes IP in phone.

It might not be possible, but wanted to ask anyway. Is there any way to do this without involving proxies or vnp? They are easily detectable.

Not possible without root or proxy. Tried it with NetGuard on a rooted phone — can force some traffic through mobile, but still a hack. WiFi always takes over by default.
