Mount azure blob container to AKS using blob-fuse with 0777 permisions

Hi,
I was able to mount blob container to AKS. However when pod is initialized, it is mounting with 0775 instead of 0777.
How should I change my yaml file below?

apiVersion: v1
kind: PersistentVolume
metadata:
  name: {{ $tenant.org_slug }}-dev-user-files
  annotations:
    "pv.kubernetes.io/provisioned-by": "blob.csi.azure.com"
spec:
  capacity:
    storage: 1Ti
  accessModes:
  - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  storageClassName: blob-fuse
  csi:
    driver: blob.csi.azure.com
    nodeStageSecretRef:
      name: azure-blob-secret
      namespace: default
    readOnly: false
    volumeAttributes:
      skuName: Standard_LRS
      resourceGroup: dev
      containerName: user-file-system
      storageAccount: dev
      protocol: fuse
    volumeHandle: fs-dev-store-{{ add 4 $tenant_index }}
  mountOptions:
    - -o allow_other
    - --file-cache-timeout-in-seconds=120
