BTLE Device Tracker problem

I’m hosting Home Assistant in docker running on an Asus PN40. Since it does not have BTLE built in I added a usb dongle supporting it.

hci0 is the built in module, and hci1 is the new usb dongle

Configuring HA to track BTLE devices I get the same error as when I try to scan for BTLE with hci0, which suggests me that it’s defaulting to that.
Also, when I ssh into the container and run “hciconfig hci0 down” I get an error in HA saying BT network is not available.

Reading the docs I can’t find a way to set hci1 as the default device for BTLE (while normal BT integration can be configured trough yaml to use hci1)

Is there a way to tell HA to use hci1?
