Is it possible to open a qsys system from the command line (in a build script) and "Sync system infos"?

I have to compile 2 product qsf revision variants of the same design including a qsys system, on different devices so this is required when building from within the Quartus GUI).

This is my current script command:

qsys-generate Qsys.qsys --synthesis=VERILOG --family="Stratix 10" --part=1SG110...

and I know I can use qsys-script to process tcl command, trouble is I cannot find a reference of available commands.

Thanks
