Disabling the SR-IOV Network Operator admission controller webhook doesn't work.
The documentation that my partner iDirect is following is this:
https://docs.openshift.com/container-platform/4.12/networking/hardware_networks/configuring-sriov-operator.html#disable-enable-sr-iov-operator-admission-control-webhook_configuring-sriov-operator

My Partner is using this network card:
Intel X710 - Vendor ID 8086 - Device IDs 1581 and also 15FF

Support case: 03427806

https://docs.openshift.com/container-platform/4.12/networking/hardware_networks/configuring-sriov-operator.html#disable-enable-sr-iov-operator-admission-control-webhook_configuring-sriov-operator

1. Execute the following commands and it doesn't yield any result:
# oc get -n openshift-sriov-network-operator sriovoperatorconfigs default -o yaml | grep enableOperatorWebhook
  enableOperatorWebhook: false

# oc patch sriovoperatorconfig default --type=merge -n openshift-sriov-network-operator --patch '{ "spec": { "enableOperatorWebhook": false } }'
sriovoperatorconfig.sriovnetwork.openshift.io/default patched (no change)

2. Try disabling an enabling the webhook but it doesn't trigger a change:
# oc patch sriovoperatorconfig default --type=merge -n openshift-sriov-network-operator --patch '{ "spec": { "enableOperatorWebhook": true } }'
sriovoperatorconfig.sriovnetwork.openshift.io/default patched

# oc patch sriovoperatorconfig default --type=merge -n openshift-sriov-network-operator --patch '{ "spec": { "enableOperatorWebhook": false } }'
sriovoperatorconfig.sriovnetwork.openshift.io/default patched

After disabling the webhook they still get "unsupported device" errors:

2023-02-02T14:34:34.155921577Z I0202 14:34:34.155874   10871 utils.go:103] DiscoverSriovDevices(): unsupported device 0000:18:00.0 -> class: 'Network controller' vendor: 'Intel Corporation' product: 'Ethernet Controller X710 for 10GbE backplane'

Being able to disable the webhook and use this network card.

Additional info and must gathers attached in the support case 03427806.

I open this bug as I have an email thread with SME and Manager of SME in Networking Development and they recommended me to file it because it's an unexpected behavior.
