WSL does not mount anything except C: at boot time.

So you need to do a manual mount inside WSL.

Example 1, using drive letter N:
First mount NFS share in Windows's Cygwin terminal:
/sbin/nfs_mount  -o rw "N" nfs://31.48.17.20//lab/lab14/rundata/

Within WSL then mount Windows drive 'N':
mkdir /mnt/n
mount -t drvfs N: /mnt/n


Example 2, using UNC path:
/sbin/nfs_mount -o rw nfs://31.48.17.20//lab/lab14/rundata/

Within WSL then mount Windows drive
mkdir /mnt/rundata
mount -t drvfs '\\31.48.17.20@2049\nfs4\lab\lab14\rundata' /mnt/rundata

Just calling /sbin/nfs_mount without arguments will print you the UNC
path for each mount.

Yes, this is supported in the upcoming release of ms-nfs41-client,
with some limitations:
- Win32 QueryInformation types FileStatInformation (68) and
FileStatLxInformation (70) are not yet implemented, so uid/gid/mode
available in Cygwin are not available in WSL yet
- softlinks do not work (EPERM), likely because WSL probes
FileStatInformation&FileStatLxInformation at start, gets
STATUS_NOT_SUPPORTED and then treats it like a FAT drive.
