Yes in 12c DNFS works on NFSv4. In fact, NFSv4 is required if you plan
to use OISP (Oracle Intelligent Storage Protocol) to talk to their
ZFSSA. Although I would not suggest using the ZFSSA to run live
databases yet. Should be OK for FRA uses.

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

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
