I'm using NFS to share data between VMs. I've already set up working jumbo frames between VMs and host. My question is - do I need to somehow explicitly tell nfs to use jumbo frames or it'll just detect possibility of using them automatically? All network interfaces have MTU set to 9000. ping -M do -s 8000 work flawlessly.
Do I need to explicitly enable jumbo frames in NFSv4?

You should mount the nfs filesystem with the rsize and wsize options set to suitable values. Check man nfs.
