Installing the driver without connecting a device

I am trying to install some unsigned outdated drivers on my computer from the command line. I used the dpinst.exe and installhinfsection functions which work fine, however all I've tried is software in the first place, meaning it installs the driver on your computer and then doesn't actually show up in the device manager until you plug in device to computer.

I want to install the driver and show it in device manager without having to connect any devices.

I can do this with legacy hardware added from Device Manager, but I want it to be an automatic process, so everything is from the command line and doesn't have to be done manually through Device Manager.

EDIT Drivers were written by me (UserModeDriverFramework), they simulate real devices.
