name: "test"
spec:
{{- if not .Values.autoscaling.enabled }}
replicas: {{ .Values.replicaCount }}

Did I am using right place for mountOptions? or anything did I made mistake in deployment file

Answer 1

Please modify the deployment.spec.template.spec.volumes.csi.volumeAttributes.mountOptions to a string of comma separated key value pairs, instead of an array.
So your modified Deployment manifest should have:
...
volumes:
- name: smb01
csi:
driver: file.csi.azure.com
volumeAttributes:
server: 10.10.10.100
shareName: share01
secretName: smbcreds
mountOptions: "dir_mode=0777" #correct format
instead of:
...
volumes:
- name: smb01
csi:
driver: file.csi.azure.com
volumeAttributes:
server: 10.10.10.100
shareName: share01
secretName: smbcreds
mountOptions: #incorrect format
- dir_mode=0777

Answer 2

In error clearly mentioned at a place of CSIVolumeSource.volumeAttributes: got "array", expected "string" it got th Array instead of String
your YAML should be like
volumes:
- name: smb01
csi:
driver: file.csi.azure.com
volumeAttributes:
server: 10.10.10.100
shareName: share01
secretName: smbcreds
mountOptions: dir_mode=0777
