Change nfs path without reinstalling helm package

[AlistairMcCutcheonIAS]

I've been using this for some time, but I need to change the nfs path that I'm using. I have several persistent volumes which I don't want to delete. As per the readme, the way to install the helm package is:

helm install nfs-subdir-external-provisioner nfs-subdir-external-provisioner/nfs-subdir-external-provisioner \
    --set nfs.server=x.x.x.x \
    --set nfs.path=/exported/path

But is there any way to change the nfs.path after it is installed please?
