is there any possible way to ban evade withouth VPNs at all ?

title, a friend of mine got pbanned right now and while me and him are trying to appeal to Discord (which i think its a useless move btw as discord doesnt give a fuck AT ALL) and he wont be using VPNs just to ban evade

I was thinking in changing the IP on Windows network settings, will that + the full ban evasion guide thing work for him ?
