Full GPU virtualization with Linux KVM

I’m working with the NVIDIA Tesla V100-SXM2 GPU and trying to virtualize my GPU under KVM with Ubuntu 20. However, the only solution I found when googling is the direct passthrough.
I need to fully virtualize the GPU, but I can’t find how to do this.
Please, can someone provide any help with this? Or at least redirect me to an appropriate support page?
