Need to Install Drivers to Latitude E6430 Windows 7 64-bit Laptop Without Wireless Drivers

Hello!

 I need to download and install drivers to a Latitude E6430 Windows 7 64-bit laptop without anykind of network/modem/wireless drivers. To be clear, I actually don't want wireless/network/modem drivers on the machine, but I'd like to update the video drivers, bios drivers, etc etc (everything but internet drivers basically). (I want this to be my offline laptop to avoid internet distractions)

However, when I go to download drivers from the website, it basically says the drivers will (A) automatically install and (B) when I tried to download anyway hoping I could just move them with my external hard drive it basically downloaded a Dell System Detect Launcher. How do I get the drivers piecemeal, put them on my external hard drive, and then install them on my offline Dell Laptop?
