SRIOV on intel iGPUs?

As we all know the 6th to 9th gen of intel CPUs or rather their integrated GPUs did support GVT-g which was similiar to sriov.
I used it very often on many different devices but with which the 11th generation GVT-g was discontinued and replaced by sriov according to intel.
But to this date I haven’t seen a single system where sriov was used for an intel iGPU and I cannot find any references or guides on how to use it online.
Am I overlooking something or is this feature pretty much not existing?

I’m looking forward to upgrade my personal laptop to a newer machine with a newer intel CPU (currently it’s a 8th gen CPU and GVT-g works flawlessly). I would really like to continue having this as an option.
Any ideas on this?
