Can Clara-FL-4.0's server initialised model be deterministic?

With specifying MMAR_CKPT in environment.json, server can start with specified weight. Other than that, it seems server would randomly initialise a server model and then distribute it to clients.

Is there other way to allow server’s initialised model be deterministic?
Also, except server’s initialised model, are there other parts in FL-work flow that cannot be deterministic?

Thanks!
