It depends on
1) which iMac you have
2) which GPU you put in the enclosure 
3) what do you mean by ‘use’

But generally speaking, internal display as a primary visual use with eGPU on iMac is not recommended.
Using them for computational purposes would be possible with some GPUs. 

Check out my build if you are interested what can be done with 2017 iMac 5k.

If you have an iMac with an iGPU only, it will work as long as you use the Windows Graphics switching. I can only speak for Intel iGPU + NVIDIA eGPUs. Not sure about AMD eGPUs. 

The drawback is is you have no access to the NVIDIA control panel or GeForce streaming/recording, but you can use the Windows gaming DVR.

Yes, it is possible, but the process is quite difficult to do it. So, I will suggest you visit and consult macbook pro won't turn on black screen
to get the required solutions regarding the booting method.

I am not sure what you are planning on using the 2080 for.
It will probably work fine for computing. But for visual use, you will most likely run into issues.

If you are looking to game with it, I can't recommend using the internal display with eGPU.
Have look on this post.

It is much easier to avoid black internal display. Follow this guide which make your internal display working
