Can I use AX6600 with Orbi?

[RobNYC]

Hi everyone. Thanks in advance for your patience as I am new here and I am half-way tech savvy but not with networking gear. I recently moved and started a new system. I got the Orbi (RBS 850) router with 2 satellites. It is working well. Someone gave me a new in the box Nighthawk AX8 (AX66600 - Model #RAX70) Tri-Band Wifi 6 Router. I would like to put it in another area of the house, and I can plug it into an ethernet port.. Can I put it in bridge mode or somehow use it as an access point with the Orbi system? Where would I go to tweak the settings since it wouldn't come up in the Orbi app, etc.

Thanks in advance for any guidance.

You can use it in access point mode but it won't integrate with the orbi system. 

What I do in these situations is set it up in access point mode and make sure its on a different wireless channels (to prevent interference). 

Then I either use it to offload the orbi by putting the devices that have fixed locations (aren't mobile), IoT devices, or even just use it as backup.
