Wyse 5070 Windows 10 IOT connection broker RDS

Hello,
I bought a wyse 5070 with Windows 10 IOT.
I have a farm RDS with broker connection.
I am trying to configure an RDP connection via WMS but I can not find the option.
Is there an option to configure a connection broker?

I would like add this option : "loadbalanceinfo:s:tsv://MS Terminal Services Plugin.1.Staff"

Thanks
