Ganesha V2.4.0 has a new "dynamic export update" feature. A specific export can be updated with dBus, and all exports in the config are refreshed on SIGHUP. With this, you can dynamically update everything except export_id, path, and pseudo, those basically imply removing the export and adding it again, so just use the dBus remove and add commands. SIGHUP will also add any new exports that have been added to the config file (it will not remove any exports - it doesn't make any check to see if any export was no longer present in the config file). The dBus update export will also add the export if the specified export does not already exist. The update process uses atomic operations to update all the fields in the export except the CLIENT blocks. The CLIENT blocks are atomically replaced (update builds a new list of clients/permissions and then takes a lock on the list and swaps the old list with the new list). The end result is that clients will see no disruption (well, if the new client list excludes a client that previously had access, of course it will lose access as soon as the client list is swapped out).
