No. The only way to copy Wii discs is through Wii homebrew which requies a hacked vwii. It has nothing to do with this injector.
I think your info is outdated. I have been inquiring with another knowledgeable person. Cant post links yet but on YouTube its
by P3NCE Look for >>> Wii U 2019 Softmod Guide - Play Games from HDD <<<
But not the video the comments below... The video he created a guide to doing the old way by Hacking vWii
However below you can plainly see that it can all be done without even going into the vWii & Wii games can be launched directly
from the Wii U Main Screen as well as gamecube games. I am already doing Retroarch without vWii…
The Following Conversation seems to contradict your suggestion...
Me:
With a Tool Like "TeconMoon's WiiVC Injector Script" can I Yet again avoid hacking the vWill and still be able to Rip my Wii CD's & install them to USB and play them on the WiiU? Its just that modding the vWill seems to be more dangerous than what I have already done to my device. But I stll want to be able to RIP my Discs whether they be WiiU or just Wii Disc's.

sledgebeast you won't be able to rip your wii games on your wii u only wii u games anyways you still need vwii to rip wii games directly to usb ........WiiVC Injector is for when you already have your ripped games on your pc to do the inject and don't won't to use vwii <<<<<<<<<<<< Here!
Me:
When you said "WiiVC Injector is for when you already have your ripped games on your pc to do the inject and don't won't to use vwii" Are you referring to Wii U Only Titles or also Wii Titles?
Isai Mireles:
sledgebeast Wii games and GameCube games only need to be injected ( injected means it’s converted to a format that it can be installed to the Wii U nand or usb) Wii U games get dumped to the install folder on the sd card when they get ripped
Me:
Ok so does that mean then that the Wii Games can be launched from the Wii U menu after that is done? Or with no vWii Hack... They appear & can be run from vWii Menu?
Isai Mireles:
sledgebeast they appear in the Wii U menu with no vwii needed << & Here!
Me:
Sweet! So that would also mean I don't need two separate USB Drives anymore. And the USB drive can be formatted WiiU...
Isai Mireles:
sledgebeast exactly now go mod your Wii U theirs a good tutorial on the whole inject thing just search here on YouTube
p.s.
Certain old models of PC DVD drives are able to rip game discs with RAWDUMP or FRiiDUMP
