As 'chmod' will modify atime, so use 'noatime' mount option. I don't think a chmod is a reliable way to recall delegations. Maybe mount with "clientaddr=0.0.0.0"? From the nfs man page: Can specify a value of IPv4_ANY (0.0.0.0) or equivalent IPv6 any address which will signal to the NFS server that this NFS client does not want delegations.
