How does one make a GPU in a brand new ubuntu 20.04 VM usable?

I've been trying all day to have this (v100) GPU working on a new ubuntu VM. I tried installing the drivers and rebooting and also purging/uninstalling everything to do with nvidia but none of these things seem to work.

In particular I ran this specifically:

apt update;
apt install build-essential;

sudo add-apt-repository ppa:graphics-drivers
sudo apt install ubuntu-drivers-common
ubuntu-drivers devices
sudo apt-get install nvidia-driver-460
sudo reboot now

Then sometimes it seems that nvidia-smi is working (as of the writing of this question it wasn't so I wasn't able to copy paste what is said when it works) but when it doesn't work it says this:

(synthesis) miranda9@miranda9:~$ nvidia-smi
Unable to determine the device handle for GPU 0000:00:06.0: Unknown Error

any help is appreciated.

Note I also do not have access to the VMs vmx file so this question and answers are useless/meaningless to me: https://forums.developer.nvidia.com/t/nvidia-smi-reports-unable-to-determine-the-device-handle-for-gpu/46835

In addition I have tried to uninstall everything from nivida and re-install it with:

sudo apt-get --purge remove "*nvidia*"
sudo /usr/bin/nvidia-uninstall

then

apt update;
apt install build-essential;

sudo add-apt-repository ppa:graphics-drivers
sudo apt install ubuntu-drivers-common
ubuntu-drivers devices
sudo apt-get install nvidia-driver-460
sudo reboot now

but that doesnt seem to work

More info in case it helps:

A virtual machine emulates a graphic card, so it should be transparent for the guest system which native card you have on your host system. VMs are for "sharing" resources - as opposed to a real system that has access to its hardware directly. So it will not make sense to install Nvidia drivers on a host system. You can check this out by checking your current drivers in your VM:

inxi -G

(executed in a terminal) will show you a VM/oracle driver, not your native card.

Getting a hi performance graphic output may be reached with tweaks and tricks, but VMs are not meant for work like this....
