With PAM4, Bit rate or Baud rate

In the setup of PAM4, do we use the bite rate or it should e the baud rate, baud rate equals half the bitrate

In Pam4 the data rate should be bitrate and not the baud rate. For example,  PCIe6, the baud rate is 32Gbaud/s, but the user must enter 64G for the data rate.
