License?
TL/DR: Please add any kind of license to the provided scripts.
Long:
I don’t see any kind of license associated with your scripts, which is problematic. I wanted to do this kind of GPU pass-through for quite some time and your scripts look like they can be a nice quick-start.
But as there is no license declared at all, I cannot legally use any script you provide. Even downloading and using them as-is is problematic and can be ruled as a copyright violation. But modifying them to suit my needs, like adjusting PCIE bus addresses is clearly impossible, as the current situation (all rights reserved) makes the files legally immutable.
The only possibility to use the provided scripts is to study what they do, look away and then re-implement them from scratch using the gained knowledge.
This is the current situation with your repository:

https://docs.github.com/en/free-pro-team@latest/github/creating-cloning-and-archiving-repositories/licensing-a-repository#choosing-the-right-license
https://choosealicense.com/no-permission/
Any kind of license will be fine, as long as it grants at least a single-user license to actually use and modify them for personal use.
BTW: If you accept a pull request under the current situation (which by itself is a copyright violation by the person who offered it), you’ll lose your right to modify the project. Because then both contributors hold the exclusive right for modification (“Only I can modify it.”), neither can modify the code without breaking the other’s copyright. This will make the whole repository basically immutable until the copyright expires in 70 years after your death.
