UHK 80 Bluetooth: How do I disable Left NUS?

I have UHK80 and want to disable Bluetooth as I do not need it.

I have a startup macro ($onInit) to turn of Bluetooth which does partially so.
But scanning Bluetooth I see one device still called “UHK 80 Left NUS” which disappears if I disconnect the UHK80. Maybe I have missed some command in the script?

Here’s my $onInit macro:

set bluetooth.alwaysAdvertiseHid false
set bluetooth.directedAdvertisingAllowed false
bluetooth noAdvertise
set bluetooth.enabled 0

Not possible atm I think, except for putting the leyboard to sleep.
