I need to connect to a checkweigher device that has an OPC-UA server module gateway unit that data can be extracted from. In preparation for when this device is installed, I am looking at the device connection options in Ignition. My assumption is that I would use the OPC-COM Tunnel Driver to connect Ignition to this OPC-UA unit to collect the data. But I wasn't sure if I was understanding if that is what this tunnel driver is for? Please advise.

No, if your device has an OPC UA server, then you just make an OPC UA connection to it. No tunnel driver involved.
