Once determined, I can add your report to my list of repeaters that do / don't work with Xiaomi / Aqara devices over in my other thread, Xiaomi & Aqara Devices - Pairing & Keeping them connected.
Just to clarify, is this the Nue Dimmer Switch that you have?
If yes, I also wonder if it possible to link / integrate the Nue ZigBee Bridge with a Hubitat Hub so that any Nue devices could be connected the the Nue Bridge to isolate them away from Xiaomi / Aqara devices.
As @SmartHomePrimer explained, ZigBee devices are free to change their network route as needed, so there's no guarantee a Xiaomi / Aqara device won't spontaneously decide to connect to an "unfriendly" repeater.
That said, some people have managed to keep their "unfriendly" repeaters far away enough from their Xiaomi / Aqara devices that they manage to coexist peacefully. I think it's just hit or mess / dumb luck, however.
