Helix Fi 2 Gateway router for wired devices

Hello Community!

A question for your all.
I am looking to switch to Videotron internet with the latest Helix Fi 2 gateway.
In my current setup, I have a cable modem connected to a Wire/Wifi Router, with a wired printer and personal cloud (NAS).

If I understand correctly, the Helix Fi 2 gateway is an all-in-one cable modem+wired/Wifi router, is that correct?

Would I encounter any issue to plug my printer and personal cloud (NAS) into the ethernet ports on the Helix Fi 2 gateway?

I could not find any clear guidance on this, and one article suggested that depending your network setup, you may need to enable "bridge" mode on the Helix Fi 2 gateway and connect to my existing router.

Thanks in advance to anyone who can help clarify my understanding.
