Change bluetooth mac address on the 19007+4631?

Is there any way to change the bluetooth mac address?

Never tested it, but Bluefruit library (part of the BSP) offers these functions:

    /*------------------------------------------------------------------*/
    /* General Functions
     *------------------------------------------------------------------*/
    ble_gap_addr_t  getAddr(void);
    uint8_t         getAddr(uint8_t mac[6]);
    bool            setAddr(ble_gap_addr_t* gap_addr);
