No, this is a limitation of Xiaomi devices and not Hubitat. They're not standard ZHA1.2 or ZLL or Zigbee 3.0.
That being said, there are two possibilities. Some people, myself included, have all of our Xiaomi devices on a separate Hubitat that only has Xiaomi-compatible zigbee repeaters (I use Tradfri outlets and USB repeaters). The other possibility is to use a Mi hub and bring them into Hubitat using an RPi and the Mi Connector app.
Edit: Just checked gearbest - the Aqara sensors are $18 a piece. Completely compatible Samsung flood sensors are just $19 a piece on Amazon. I would recommend getting the Samsungs.
