ESP-WROOM-32 ADC0 & ADC3

Can ADC0 and ADC3 be used on the ESP-WROOM-32, since those pins are internally connected via 270 pF caps to the SENSOR_CAPP and SENSOR_CAPPN pins on the ESP32? I read that the 12-bit conversion time of the ADC is about 166 us, is the conversion time reduced on those two pins due to the caps? Thanks.
