[Helm Chart] PVC only for Data (File) Storage

I want to install Nextcloud on a Kubernetes Cluster via Helm Chart.
Is it possible to have 1 PVC for all Nextcloud Instances where all Files are stored on an NFS ?

My Problem is i cant enable nextcloudData.enabled without persistence.enabled.
But i dont want everything under /var/www/html on my NFS just the Files.
