NFS Datastores change from read-write to read-only

[Algon2]

Hiya

Hopefully a quick and simple one. 

ESXi v7

Vcenter v7

Is there a way to change an existing NFS connected datastore from RW to read-only or am I going to need to disconnect it and re add it?

Thanks in advance

Hi

There must be a way to set a Datastore as read-only post creation?

Thanks
