Yes, there is an option to generate a compressed SOF in Intel® Quartus® Prime Pro Edition Software starting from version 20.3 and above for Intel® Stratix® 10 and all Intel Agilex® devices.
This option just reduces the size of the SOF file, and is off by default. The raw bitstream for Intel Stratix 10 and all Intel Agilex devices are always compressed irrespective of this option.
To enable the “Generate Compressed SOF” option, go to the General Tab under Device and Pin Options setting in the Intel Quartus Prime Pro Edition Software.
The information is scheduled to be included in future releases of the Intel Agilex® Configuration User Guide and Intel® Stratix® 10 Configuration User Guide.
