FS6500 SBC disable Watchdog and RSTB during flashing process

I have the following hardware configuration FS6500 and MPC5777C. My application configures the SBC to have INIT_FSSM and INIT_FAULT reaction to trigger FS0B and RSTB as well as the FCCU lines ERROR_0 and ERROR_1 (IO_23) on the SBC side.

 

My question is: What can I do to disable the SBC watchdog if I want to go to a Programming state (this will jump usually to a bootloader)  to execute ERASE and FLASH process?

 

Also, is it possible to disable the WD operation at anytime? 

 

Thanks!
