With USB dongles, the way to do BLE stuff is to access the dongle from userspace on the raw USB level.
The kernel bluetooth stack would use classic non-LE Bluetooth only.

I've had https://github.com/noble/noble working about three years ago, even contributed patches for FreeBSD support.

Also https://gist.github.com/myfreeweb/44f4f3e791a057bc4f3619a166a03b87 is a devd config for not attaching the kernel driver automatically.
