Access ONT after bridge mode

[wireless]

Just had TELUS fiber installed. I've set the ONT to Port 1 Bridge mode.
I have 2 different routers connected to Port 1 (dumb switch between).
Both are up and working perfectly. However I can't get into the modem from within my network.
I connected my laptop to the 10G port and was still able to get into the ONT from that, but I think that caused the other devices to drop off.
What is the best way to admin the ONT after bridging it?
