Not being familiar with the iRig, I can't be sure, but probably. There are quite a few hubs that support power passthrough. As long as the hub has more than one USB-C port, it should work. Further research is recommended for choosing a specific device. I don't have enough information to make suggestions.
My own hub does pass through power, but it only has a one USB-C port, so I can't attach another USB-C device and power at the same time. It also gets really warm, so I don't trust it for long use.
