if i using x264 2-pass mode, how to set QP=0? or QP=0 can only set in CRF mode?

There is no way to combine --qp=0 and 2pass encoding.
If you want lossless encoding with x264, you would have to:
  • set "x264->Base->Restriction Settings->AVC Profile" to either 'High4:4:4' or 'None'
  • set "x264->Base->General Settings->Encoding Mode' to 'constant quantizer (1-pass)'
  • enabled "x264->Base->General Settings->Lossless'
this way Hybrid would use --cq=0.
