Hello. I am using Cinema 4D with a render system Cycles 4D, the rendering process is based on CPU and GPU as well. As far as I understand I can connect up to 4 eGPU devices to speed up the process of rendering. Would it be possible to connect Nvidia eGPU to the 2019 IMac?
Thank you for your help in advance.

If you need NVidia you are limited to Keplar cards. The Quadro K5000 and GTX 680 Mac Editions are officially endorsed by Apple (https://support.apple.com/en-us/HT208898), but if you don't need boot screen support via the eGPU then any Keplar card should work. (GTX 780, Titan Black, etc).
Edit: Never mind. Apple has restricted official eGPU support to AMD only so 3rd party software is needed to use Nvidea cards as eGPUs even when native drivers exist.
Here is Apple's article on eGPU and what is supported:
Use an external graphics processor with your Mac - Apple Support
Looks like only Radeon-based GPUs are supported.
All I know is contained in the Apple article I linked. Requests for unsupported hacks here tend to get quickly zapped so you'll need to look at other sites, especially gaming sites that have sub-sections devoted to GPU support.
Stick with an AMD GPU at this time. Some have managed to get
Nvidia but not without some hack that can cause some
system instability or break with some OS update.
Thank you, but, is there opportunity to connect a NVidia GPU?
External Nvidia GPU.
