Set no_root_squash for all volumes in an SVM

New to Ontap.   I have Trident and NetApp configured.  I have an SVM with an export policy that looks like 

svm_nfs_prod prod_root 1 any 10.X.A.0/24 any
svm_nfs_prod prod_root 2 any 10.X.B.0/24 any
svm_nfs_prod prod_root 3 any 10.X.C.0/24 any
svm_nfs_prod prod_root 4 any 10.X.D.0/24 any
svm_nfs_prod prod_root 5 any 10.X.E.0/24 any
svm_nfs_prod prod_root 6 any 10.X.F.0/24 any

I want to set no_root_squash but cannot find a KB article that works.  The following link says "How to confiugure" but it does not say how to configure.  Instead it  includes details of how to show existing export policy rules.

Can anyone point me to a one line command that will set no_squash_root for my svm_nfs_prod and for the six  networks in the existing policy?

Thanks
