Hi, 
 It is possible to remove the signature requirement from the secure bootloader examples, but then you should not use the same Service UUID as it is reserved for the secure implementation (I.e., DFU with signature requirement). You may use the nrf_dfu_req_handler.c file from the open bootloader as reference to see how you can disable the signature check (req handling should not be transport depentent). Note that the open bootloader still require signature validation for bootloader updates.
