Hardware Update game without updating console?

[NanoBunTV]

So, I have a modded console, and I have the DNS servers set to ones that block system updates. Today, I got a copy of Guitar Hero LIVE and it requires a game update before you can use any online features, but I don't want to set the DNS servers back to default and loose access to homebrew (cause system updates make you loose access to it) just to update the game to use online features.

TL;DR: Can I update a game (a disk game) without setting the custom DNS servers back to normal and risk my system updating? Like a force update, through something like WUP Installer maybe?

Nevermind, I found a software called NUSGrabberGUI (New NUSGrabberGUI, to be exact).

could also use NNUPatcher which is something you launch from the homebrew launcher than allows eshop access

I know, I already have NNUPatcher, forgot you can get updates from e-shop lol
