My motherboard bluetooth chip is weaker, and have dongle which gave better range. Previosly I found solution here (long time ago, maybe on ubuntu 18) -> Deactivate internal bluetooth adapter while leaving usb dongle online

With which I excluded motherboard chip, but now on ubuntu 22 i tested is not working. It's modern now, shows 2 adapters, how can I exclude one (motherboard) adapter and choose dongle.

To select a default bluetooth controller you can use the bluetoothctl command which directly talks to the bluez stack that Ubuntu uses by default:

bluetoothctl list

Which will list your bluetooth controllers and their MAC address, then select the one you want as the default using it's MAC address:

# replace with your controller's mac address
bluetoothctl select 00:11:22:33:44:55

You may have to turn the power on your bluetooth controller after setting the default controller, which you can accomplish using this command:

bluetoothctl power on

You can find more information here: https://ubuntu.com/core/docs/bluez/reference/pairing/introduction

In general though your solution should involve going through bluez rather than through udev.

Disabling a bluetooth adapter at the kernel level is overkill. I have multiple bluetooth controllers connected to my system and have never had to mess around with udev to get them working.
