MAX 10 Modular ADC core problem with reserved pins

I want to use only TSD (temperature sensor diode) to monitor chip (10M50SAE144I7G) temperature. When I instantiate 'Altera modular ADC core' in my project with all channels disabled except TSD, fitter says that dedicated input pins ~ALTERA_ADC1INx~ is assigned.

Error (176310): Can't place multiple pins assigned to pin location Pin_8 (IOPAD_X0_Y36_N14)
    Info (176311): Pin E100_RX_DV is assigned to pin location Pin_8 (IOPAD_X0_Y36_N14)
    Info (176311): Pin ~ALTERA_ADC1IN3~ is assigned to pin location Pin_8 (IOPAD_X0_Y36_N14)

Is there way to disable pin assignment for unused ADC input/channels?

From datasheet:

You can use the dual function pins in an ADC block as general purpose I/O (GPIO) pins if you do not use the ADC.

So, if i use ADC block only for TSD... I can not use these pins as GPIO?
