Unity CSI driver for kubernetes using a local image registry

Is it possible to install the CSI driver for unity from a local image registry .

I checked the offline installation 

https://dell.github.io/storage-plugin-docs/docs/installation/offline/

the customer already downloaded the images to the local image repository 

can we just modify dell/csi-unity/master/helm/csi-unity/driver-image.yaml file 

# IT IS RECOMMENDED YOU DO NOT CHANGE THE IMAGES TO BE DOWNLOADED.
images:
  # "images.driver" defines the container images used for the driver container.
  driver: dellemc/csi-unity:v1.5.0

or customer has to follow the complete offline install procedure  ?

Any way to change the pointed from docker hub to local image registry just by modifying some files
