Is it possible to change on air address (access address) for BLE using S110

I would like to hide BLE advertising from normal BLE devices. And only be able to see such advertising with dedicated scanner.

I was thinking of changing access address from 0x8E89BED6 to something else which would hopefully cause normal ble scanners to ignore such advertising.

Is such thing possible? Should that be done by changing NRF_RADIO->PREFIX0 and NRF_RADIO->BASE0 registers?

I'm using S110, and changing value of this registers causes hard fault. Is there a way to do such a thing?
