HifiBerry DAC+ ADC - Turn off DAC

Hi,

I'm using the DAC+ ADC for a project, but I really only need the ADC. Is there a way to turn off the DAC? I've tried bending the power pins (AVDD, DVDD, CPVDD and LDO0) up to disconnect the whole IC, but then my Pi Zero doesn't recognize the board anymore. In dmesg I get:

snd-rpi-hifiberry-dacplusadc soc:sound: ASoC: failed to init link HiFiBerry DAC+ADC: -517
