Setup Nvidia P40 GPU in Windows Server 2025

We are trying to install and configure a GPU in Dell PowerEdge R730 test server, Windows Server 2025 Datacentre, version 10.0.26100 build 26100.
Hyper-V is installed and configured with 10 VMs setup and working but we require a GPU that will allow GPU partitioning to share the GPU with the VMs.
In Device Manager (on the host), under “Other devices” or “Display adapters,” all we can see is the “Microsoft Basic Display Adapter” entry but no P40 card.

Tried various drivers from the downloads section of the portal but none install because they do not detect the P40 card so need help in identifying the problem or a suggestion of what card will work.
