How to Deactivate Specific Inputs channels from a device with more than 32 channel?

I everybody



I successfully merged Avid Eleven Rack + Presonus Studio Live 16.4.2 + Firestudio Project (The last two using daisy chaining) like one only Device using Pro Tools Aggregated Device.



Now my problem is that I have 50 Channels but PT10 only support the first 32 channels.



I wish to use 5 channels of Eleven Rack + 8 Channels of Firestudio + 19 Channels of SLive (32CH Total).



Somebody know how to Disable some Input and Output? (In my case the Input 5/6, 17/18 and Outputs 11/12, 13/14, 15/16).
