HELP! backup order.

So My JR keeps freezing and I need a solution quick.

Do Cobalt desks on 8.2+ work as EOS in backup mode, where it's recommended to have a RPU as main and the desk as backup so the RPU do the hard work and if it crash the desk takes over?

I have a nomad and my JR and wonder if that would work.

I may call ETC if I don't get a answer soon. I have critical shows with busking and my desk is not happy.
