You probably mean GPU sharing. To which leesteken responded accordingly.
vGPU is a form of GPU partitioning to enable "sharing" one GPU amongst more than 1 guest.
Read up on the subject to understand it better.
I do believe that you won't be able to use the physical output device/s of the GPU for both VM's at the same time with vGPU technology - since vGPU basically splits up the CPU time slices of the GPU - so it is good for sharing the "processing power" of the GPU - not the physical output device. But vGPU is an evolving technology - so you will need to first check exactly what you want to achieve with these 2 VMs sharing a GPU.

Exactly, like you do for vmware, I was asking if it is possible to share the resources of a Single physical GPU, between two VMs, without having to undergo Passthrough, dedicating the resource only to one VM
Yes it is possible with NVidia server GPUs: https://docs.nvidia.com/vgpu/latest/index.html . That is why I posted the link to the Proxmox Wikl that explains how to set it up.
If you need only OpenGL support, you could look into VirGL/virtio-gl: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#qm_display
Well, first off, you didn't say which NVidia card you had, and I do mean "card" and not GPU and here's why. There are cards that have multiple GPU's on them. Those can be split up to multiple VM's. Let's say its a 4 GPU card ($5k-$10k), then 2 VM's can each get 2 GPU's, or 1 VM gets 3 GPU's the other VM gets only one GPU. You did not mention which card you have. If its a consumer grade "gamer" card it will only have one GPU (albeit really fast still only 1) and can only be assigned to one VM.
