Have you tried setting ControllerMode = le in bluez¹s main.conf?  If set,
bluetoothd will explicitly enable le and disable br/edr in the kernel via
the management interface, and that should set advertising flags
appropriately.  There does not appear to be a DBus API, probably because
this is more of a static setting.
