The ENABLE_NCONFIG_FROM_CORE sounded a little too good to be true. From Altera:
"The ACF variable ENABLE_NCONFIG_FROM_CORE was actually only applicable to MAX 10 devices and, after a little digging I've found that this variable is actually no longer supported and has been removed as a feature.
"There is no way to toggle nCONFIG from within the core of our FPGAs other than via the Remote Update IP."

Well that is too bad. In the past when I had to implement this programmable reconfiguration, I explicitly connected the nCONFIG pin on the FPGA to a GPIO port on a microprocessor; or in another case the microprocessor had control of the JTAG interface, and we were able to issue the PULSE_NCONFIG JTAG command to force the reconfiguration to occur.
