Please Help: My Ubuntu(VirtualBox machine) Does not detect my GPU NVIDIA

I want to install nvidia drivers CUDA, Cudnn (for Deaplearning), on Ubuntu (Virtual Machine). and I have 2 GPU installed in my physical machine(windows OS) and you can see them in my device manager :

-Intel(R) UHD Graphics 620
-NVIDIA GeoForce MX110

Here is the screenshot:

I already succeeded in the installation of NVIDIA drivers (by switching from an Intel card to Nvidia using the NVIDIA control panel), then the installation of CUDA and Cudnn (for Tensorflow), on Windows and it is perfect: I can now use Tensorflow on my local machine using Anaconda, Pycharm...

But, now I need CUDA and Cudnn installed on my virtual machine VirtualBox (Ubuntu), because I have to use the linux command line (for a tokenizer...)

The problem is that I tried all the methods (for example, this link)

But the problem is: Ubuntu doesn’t recognize my graphic cards (especially NVIDIA card that I need to install CUDA and Cudnn...)

and when I query my own graphics card model, it doesn’t recognize the NVIDIA card. Here's a screenshot:

And when I type : sudo ubuntu-drivers devices this is the result:

And when I go to "Additional drivers", it shows me this (that my cards are not working), and even when I try to check "continue using a manullay installed driver", I can’t save the changes.Here a screenshot:

in other words : How to enable the passthrough from Windows as Host Operating System to Linux (ubuntu) as guest OP (on VirtualBox Machine) and Thanks. Thanks in advance!
