Verizon 5G Home Broadband: Can it Connect to Googl...

Verizon is bring fiber into our community this summer and the village where I live is negotiating the "last mile" in the streets to deploy their Home 5G Broadband. My question is will I be able to connect my Verizon router into my existing Google WIFI mesh and shut off Verizon's WIFI? If so, will there be a speed hit? As I am currently 80 down and 20 up, 300 would be a dramatic improvement.
