Gen 6, 7, 8, and 9 for intel and all Ryzen from AMD were designed for windows 10 and newer OS's. You will be hard to find any official drivers from manufactures to support win 7 on newer hardware.
You might be able to download the windows 10 version of the driver then run it in a compatibility mode for windows 7 to install.
The other option is if that is a valid windows 7 key for that computer you can download the windows 10 media creation tool and upgrade that key to windows 10 on the computer for free.
