How to enable Vybrid TCON Spread Spectrum?

Our product fails EMI testing because of the display pixel clock. We're using a TFT with TTL interface, controlled by the DCU and TCON drivers. I wonder if it's possible to enable spread spectrum for the TCON module. From the VybridRM I don't understand how the pixel clock is generated. The TCON module has its own Timing Signal Generator (TSG). Is the TSG related to the Clock Controller Module (CCM)? If I enable spread spectrum for PLL1 or PLL2 in the CCM, will this affect the TSG? If not, is there another way to enable spread spectrum for the TCON module?

 

Thanks for your help
