Cannot find the parameter CBRK_IO_SAFETY

[Yifever20002]

I have successfully uploaded the px4_fmu-v5_default.px4 to QGC. However, in the Parameters interface I cannot find the parameter CBRK_IO_SAFETY, which has been defined in src/lib/circuit_breaker/circuit_breaker_params.c (other parameters in this file can be seen otherwise). There is another question about motors. Having chosen the airframe 'Hexarotor x with tilted arms', there's only 4 motors in total. More details can be seen in screenshots below. Looking forward to your advice！
