Does the body diode drift? Can the SiC MOSFET be used without external Schottky Barrier Diode (SBD)?

The diode is drift free. It can be used without an SBD.
It is recommended to use synchronous rectification (turn on the channel in diode mode after a short dead time) to benefit from low conduction losses

Hope that helps ...

The answer to this is very simple: because their diode is not free of drift...
