Set Bluetooth name via Service

I'm looking for a method of changing the bluetooth interfaces name in a way that persists through power cycling without modifying onInit() or setBootCode()
I have already used

NRF.setAdveritising({},{name: "<name>"});

however it does not persist through power cycling and whilst I have found a way to make that happen using the following code:

E.setBootCode('NRF.setAdvertising({},{name: "<name>"});',true);

It is still removable with reset(true).

I can't use any methods that write to the onInit() function or E.init() handler as existing data there would be erased, so my question was whether writing to the 0X2A00 service (that defines the name), can be done at a lower level either via a puck, the web IDE, or a raspberry pi using the bluepy library.
