Ndisplay deloyment on render cluster

Hello,
I d like to use unreal in a cave ™ system on 3D.
1 master node
10 slaves node
on the nDisplay 4.27 I have not to install unreal on the slaves node. just start the listener.
What happen now with the switch board and the Ndisplay on version 5
Shall I have to install unreal on each node?
shll I just have to copy and past a folder
thx
best regards
Sébastien
