Balance Pro 30 and Verizon Band 66

Is there a way to access the Verizon band 66 with my Balance Pro 30? I am running Current firmware version: 8.1.3, which should be the most current.

Is there new hardware? Firmware that will allow this? Other routers?

Pop a BR1 Mini onto the WAN port or a MAX Adapter on the USB Port - they support B66
