As of Oracle Database 12c, dNFS works with both NFSv3 and NFSv4...KJ

I don’t believe DNFS is certified to work with NFSv4.

    When using NFS underneath ASM, I've witnessed filesystemio_options
    being honoured by the database, which means it needs setting it to
    'setall' for the combination AIO+DIO. Which makes sense, because
    you need to create a file on a (NFS) filesystem to be used as ASM
    disk device.

Then it becomes important to know which NFS?
I believe DNFS behaves different than standard NFSv3 which may be different again from NFSv4
