XPS 8930, Windows 11, how do I permanently get rid of All KILLER related apps and drivers?

After updating to W11, these awful KILLER apps and processes have returned and reduced my upload speed to less than 1mb!!! Normally I get 30mbs up. Now simple pages won't load. 

Dell XPS 8930, 32 gbs RAM, Intel i9. x64 W11 Home 24H2, OS 26100.6584, WIRED Ethernet direct to router/modem. The ethernet adapter is Killer E2400 Gigabit Ethernet Controller.

The same thing happened in W10 on same machine but problem was fully solved by the KillerSoftwareUninstaller tool, which also disabled Killer permanently from coming back on every single update. I didnt have to reinstall any drivers or anything.

However, I tried the same tool after the update to W11, and it removes Killer, and everything works better for a day or so, then suddenly everything slows down and Killer is back.

PLEASE help me get this awful suite of useless Killer tools off of my machine forever!

Thank you!

Additional info/updates:

I contacted Intel (who owns Killer) and they said this: "Windows 11 maintains a driver store cache that can automatically reinstall what it considers "preferred" drivers, even after you've removed them. The system recognizes your Killer hardware ID and keeps pulling that branded driver through Windows Update, completely overriding your manual removal efforts. This explains why the KillerSoftwareUninstaller works temporarily but then everything reverts after a day or so."

"You probably need to perform a clean driver installation process that involves purging the entire driver store of Killer-related files, blocking Windows Update from auto-reinstalling them, and replacing them with Dell provided drivers rather than Intel generic drivers (since Killer hardware is actually based on Intel chipsets)."

"We suggest reaching out to Dell Technologies for assistance with downloading the appropriate OEM driver for your specific system. Dell is best equipped to assist with OEM-specific products and can provide more specialized guidance for your particular system configuration."

I don't know how to do any of the above so I am hoping someone can help with step by step instructions OR provide other solutions. 

Thanks again!
