Connect ONT and router to patch panel

Hi

I'm using fibre internet for my home networking. The current setup looks like this:

ONT -> Nokia ONT -> patch panel ----wall----> Telus WiFi Hub -> Google Wifi Router

[ --------- garage ------------]            [----------------living room-----------]

I only use the Google WiFi network.

(I think the Telus WiFi Hub is a modem + router box. Please correct me if I'm wrong)

Everything works ok, but I also hope to use the ethernet ports through the house. One option is to relocate the Telus WiFi Hub to the garage to have:

ONT -> Telus router -> ethernet switch -> patch panel.

[-------------------   garage -----------------------]

The only problem is that the Telus router doesn't fit inside the NBN box, so I need to wall mount a small rack next to the NBN box to hold the Telus router and deal with ventilation/dust/moisture problem in the garage (unless the Telus router is less sensitive to these). I think this will work, but it's ugly. Would you recommend other solutions?

Thank you!
