Yes and if you search these forums for fios, you will find several identical questions that may have some helpful extra information for your situation. Remember to move your other wired devices to the LAN ports of the MX64 so they pass through it and you can see/control what they are doing.
In terms of the physical connection between the MX64 and the Verizon Fios, you should connect the MX on the LAN side of your Verizon device. Ultimately, Verizon will still be your outbreak to the internet.
In terms of configuration, it will depend on your needs:
--- If you want the Verizon Fios to manage your public IP address ---
With this approach, you do not need any additional configuration in the Verizon Fios device. The MX will obtain an IP address from the DHCP server upstream and it will be able to work perfectly fine. I would recommend you set a static IP to the MX in both Verizon Fios config and the Meraki dashboard for possible future implementations you might want to do.
--- If you want the MX to manage the public IP address ---
Here you will have to go to the Verizon Fios device and configure it as bridge mode. With this, the ISP will provide the public IP address to the MX and you will be able to access the MX directly from the internet without any additional configuration. After that, you should not do any additional configuration in the MX to bring it online.
