I also would do the same, typically I use an USB-Drive or ssd to backup my drivers, so in case I fagged up Windows or want to re-install it I have my drivers. I update my folders with the newer drivers mostly asap, so you only need to download stuff once and you can install everything offline. Before I would go online I suggest to configure windows and then after that enable internet. I not only do this on Windows, I in general suggest this, just in case.
