Installing a BGW210 without an ONT.

I ordered 1G service for a new house. It has an AT&T fiber port inside. There has never been an ONT on this house. There was an old POTS line NID but AFAIK there has never been an external ONT. He kept asking me about a small box inside with blinking lights. There is nothing inside that house. It’s empty. I just bought it yesterday. He even said he is required to run “an electrical systems check” before he agreed to send a technician. No equipment was found because nothing is connected to the fiber port! I called order support who they sent me to loyalty who sent me to tech support. When I told the guy the only thing I have is an AT&T branded fiber optic port on the wall with the fiber coming through and terminated inside the green connecter then snapped into the beige housing he kind of became dumbfounded. I then told him you can visibly trace it from inside the house (because it comes right through the wall and terminates as a fiber port) and up the pole (5 feet from the window) to the node/switch on the trunk line he was further mystified that I was sent a BGW210. He set an appointment up for Tuesday morning. Am I going to have a struggle to get the correct gateway or are they going to drop me back to copper? My current internal network is all 10G (OM4) fiber. Even my APs use 2.5GbE ports. I’m ok with using a high quality shielded CAT 6a or better cable to connect the BGW320’s 5G port to my network, but I’m not ok running CAT5E from a newly mounted box outside through another randomly drilled hole. It seems like a regression in AT&T’s build-out scheme
