In MAX 10 device, these nSTATUS, CONF_DONE, and nCONFIG pins are dual-purpose pins.

During configuration, these pins function as configuration pins. However during user mode, these pins can be use as regular IO.

You can set the options to turn on and off the dual-purpose function for these pins in Quartus II.

You can refer the details from the pin connection guidelines:
