Your question is a little confusing. If I understand correctly, you just want a channel to have an input source that is not AVB or USB. If that is the case just select the channel, then Select Analog or SD card. You have 4 options of input source type.
USB sends are on for every channel all the time. USB sends are not the same as USB input source type. USB sends are so you can have an analog input at the console or an input via AVB from a stagebox and still be able to multitrack record to a computer via USB.
