Is DMZ the same as IP Passthrough? I used the later because Bridge mode is apparently not an option with Cogeco
There are some cases where your Internet Provider will not allow you to put the modem into bridge mode. Usually this is because they are actually using that yellow private network to deliver additional services to you. In the case of Cogeco, that yellow network actually gets transmitted over the coax cables in your house using a technology called MoCA to deliver TIVO services. If you turn that off, your Tivo stops working which is probably a bad thing. Instead your modem may have a feature called “IP Passthrough” which lets you keep the router enabled, but at the same time passes through a Public IP address to your mesh router. It’s the best of both worlds, if your modem supports it.
Data tells me Eero is the best Wifi 6 Tri-Band Mesh but to each their own preference! 
Thanks for your help!
