Flash programming for 2nd FPGA on Arria V GT FPGA Development Kit (DK-DEV-5AGTD7N)

I am referring to this eval board:

https://www.intel.com/content/www/us/en/programmable/products/boards_and_kits/dev-kits/altera/kit-arria-v-gt.html

It has 2 FPGAs on it.

The flash device holds 2 hardware images for the 1st FPGA. Which one is loaded at power up is selectable with a switch.

However I don't see how to load the 2nd FPGA. I hope JTAG programming is not the only way to load the 2nd FPGA because that would not be permanent.
