If you want the Quadro card and the GeForce card working together, follow these instructions. If your eGPU is also a Quadro card the card should be plug and play, requiring only drivers and software for the enclosure. These instructions should work for anyone wanting to run their system with a Quadro GPU and a GeForce eGPU. In theory, it should also work the other way around, but your mileage should vary.
- Download and install the NVIDIA studio drivers on the laptop.
- This step may be able to be skipped, but better safe than sorry.
- If using a Quadro eGPU with a laptop that has a Quadro GPU, this step should be skipped.
- If using a GeForce eGPU with a laptop that has a GeForce GPU, this step should be skipped.
- If using any eGPU on any laptop that has only an Intel iGPU, this step must be skipped.
- The Studio drivers from NVIDIA (which can be found when looking for regular GeForce drivers) contain the drivers for both the GeForce cards and the Quadro cards.
- GeForce cards are supported starting with the Pascal (10 Series) architecture and up.
- Quadro cards back from 2012 (!) to present are supported

- Plug in the eGPU and authorize connecting to the device with the Thunderbolt control software.
- If mixing Quadro and GeForce GPUs/eGPUs, the enclosure should be detected with a GPU present, but the drivers for the GPU won't be loaded (yet).
- Disable the Quadro dGPU in the device manager and reboot the computer.
- This will force the computer to load the drivers for the new eGPU so we can install the correct drivers
- Install the NVIDIA studio drivers for the GeForce eGPU.
- Installing GeForce Experience is wasted here, so don't install GeForce Experience.
- Re-enable the Quadro dGPU in the device manager and reboot the computer.
- This will force the computer to load the Studio drivers for both cards and start both GPUs at the same time.
- Both GPUs should now load correct drivers and be visible.
None included here as this really only verifies functionality of having a Quadro card mixed with a GeForce eGPU with both cards enabled.
This procedure allows for running both the Quadro GPU and the GeForce GPU at the same time, on the same system. It also verifies that it is possible to do this.
@malik_zenon, Better graphics switching, for one, as you don't need to disable the Quadro in Device Manager. If gaming, you can also dedicate the Quadro to Physx to take some strain off the eGPU when gaming.
The main reason I went that route is so that I could just unplug the device and have the dGPU in the laptop still ready to go and not have to worry about making sure the device is disabled. The Studio Drivers make mixing a Quadro and GeForce GPU truly plug and play.
