​You don't.  All NFS-related configuration stuff goes into /etc/exports by
default. Including ZFS stuff.  Just treat ZFS like any other filesystem
when it comes to NFS, and configure it just like any other filesystem.

If, and only if, you want to play with the ZFS property "sharenfs", then
you can.  You aren't required to (and probably shouldn't as the syntax will
be different for every OS and may cause issues with replication to other
pools).  If you do, then anything you put into that property will be
automatically copied into /etc/zfs/exports.

You should never be manually editing /etc/zfs/exports, as any manual
changes you make will be lost the next time you edit any "sharenfs"
property on any ZFS filesystem.
