+## Flavour-specific node group overrides
+
+There may be situations where node groups with certain flavours require different config
+options to the `nodeGroupDefaults` configured for the cluster e.g performance tuning options
+which should only be applied to flavours with GPUs. This can be done by overriding 
+`azimuth_capi_operator_release_overrides.config.capiHelm.flavorSpecificNodeGroupOverrides`, which
+is a dictionary with [fnmatch](https://docs.python.org/3/library/fnmatch.html) patterns for flavours
+as keys and CAPI node group config objects as values. For example, to apply CPU pinning to any
+flavour that has a name ending in `.gpu`, you would set:
+
+```yaml  title="environments/my-site/inventory/group_vars/all/variables.yml"
+azimuth_capi_operator_release_overrides:
+  config:
+    capiHelm:
+      flavorSpecificNodeGroupOverrides:
+        '*.gpu':
+          kubeadmConfigSpec:
+            files:
+            - path: /etc/kubernetes/patches/kubeletconfiguration0+strategic.json
+              owner: "root:root"
+              permissions: "0644"
+              content: |
+                {
+                  "apiVersion": "kubelet.config.k8s.io/v1beta1",
+                  "kind": "KubeletConfiguration",
+                  "cpuManagerPolicy": "static"
+                }
+            joinConfiguration:
+              patches:

+### Example flavour-specific config for Intel PVC flavours
+
+Below is an example config for flavours with Intel PVC nodes (here identified by the `.pvc.` string),
+including Kubernetes performance tuning options, a KubeADM pre script for installing PVC drivers and
+taints compatible with the ExtendedResourceToleration admission controller to ensure that only workloads
+making resource requests for GPUs are scheduled onto the nodes:
+
+```yaml  title="environments/my-site/inventory/group_vars/all/variables.yml"
+azimuth_capi_operator_release_overrides:
+  config:
+    capiHelm:
+      flavorSpecificNodeGroupOverrides:
