I own an HP Z840 Workstation with a Quadro M6000 graphics card in it. In its day it was a spitfire system and it still works really good.
Recently, I acquired a Quadro RTX 3090 GPU. It's a large card, as I am sure many of you know. I am not sure it will work in my computer and after opening the case and seeing how dug in the Quadro M6000 GPU was in there, I was not sure I wanted to go through the headache of installing it although I want to tap into its processing power.
I also have an HP laptop (with Thunderbolt 3) and was considering getting an eGPU enclosure to use the 3090 with it. Then I came up with the thought that if I get the eGPU enclosure, maybe I can plug it into the Z840 Workstation as well. The Z840, unfortunately, does not have Thunderbolt 3. It does, however, have a Thunderbolt 2 PCIe card installed into one of the PCI slots. Thunderbolt 3 is required by the eGPU enclosure.
Here are my questions:
1. Can I install a Thunderbolt 3 PCIe card into the Z840, and if the answer is yes, which one? Is there an official one HP recommends?
2. Can I then use the NVIDIA Quadro RTX 3090 mounted into an eGPU enclosure (such as the Razer Core X) plugged into the a Thunderbolt 3 card in the Z840?
3. If the answer is yes, will 3D rendering software that supports multiple GPUs) take advantage of both GPUs?
4. Does HP make eGPU enclosures?
Would you let me know the answer to the questions above. Thank ever so much and I look forward to hearing from you.

Answer of your last Q.
Yes, HP does make eGPU enclosures. In fact, they have a few different models available. The first is the HP Omen Accelerator, which is a Thunderbolt 3-based enclosure that can house a full-length, double-width graphics card. It also includes a 650W power supply and has a built-in fan to keep your card cool.

the nvidia 3090 depending on the board maker will draw 450 to 480 watts for the factory overclocked models
i do know some HP partners/resellers are selling z840 systems with the stock nvidia 450 watt 3090 cards installed
if you go this route you will need the upgraded
