DS90UB962-Q1: Is ti962/933 support spread setting by device register?

Tool/software:

Hello TI,

We are using ti962 to connect 4 camera(ser is ti933) . We would like to find out register for spread but nothing find except for this:

       As an option for mitigating EMI / EMC, the DS90UB962-Q1 is capable of tolerating a REFCLK with spreadspectrum clocking (SSC) profile with up

      to ±0.5% amplitude deviations (center spread) or up to 1% amplitude deviations (down spread) and up to 33-kHz frequency modulation from a clock source

Is ti962/933 support  spread setting by device register? Thanks.

Thanks.
