DRA APIs have been enabled in OCP 4.21[1]
There has been some work done earlier to test the integration of DRAAPIs on an NVIDIA GPU in OCP-4.20 by Abu[2]
We have the NVIDIA Gpu operator available only till OCP-4.20 and not yet for OCP-4.21[3] in the software catalogue

So, the idea here is to deploy the nvidia dra driver via helm and test the downstream enabled DRA APIs on the NVIDIA GPU.

Reference to install the NVIDIA GPU Operator via helm:
DRA driver installation on Openshift: https://github.com/NVIDIA/k8s-dra-driver-gpu/pull/82/changes 
SCC fix for Openshift: https://github.com/NVIDIA/k8s-dra-driver-gpu/pull/569
