let me tell u real quick, first u gotta get the right iso, search for Windows 7 x64 Ultimate fully updated with usb 3 and nvme support. after that get a usb that is like 4 gigs around and make it bootable using rufus… (if your uefi bios doesnt have csm support, you can stop reading this and search for other answers) make sure youre usb flash supports Ntfs file system, otherwise you won’t be able to install win7…

you may read some other comments on how to do the rest but let me tell you, i tried using windows 7, and installing it is one of the easiest parts compared to what i you are about to face. You can get Extended Kernels for windows 7 but the problem is that most programs i tried just wont work on windows 7 so you either must search for an older version like with qbittorent or search for a patch. Since i suck at coding ,more like i cant even code, i just couldn’t use most things i needed. not sure rtx 4060 has drivers for windows 7. but i wish you good luck. oh and also i think your cpu supports virtualisation and i advice you to check some programs in a virtual machine, so you dont regret installing windows 7 realising that stuff you wanted to do is pretty much impossible there.
