No, it's not possible

too bad. On Arduino it is possible with some boards on Arduino.


#include "esp_adc_cal.h"  

 esp_adc_cal_characteristics_t adc_chars;
 if (val_type == ESP_ADC_CAL_VAL_EFUSE_VREF) {
    vref = adc_chars.vref;
  }
  float voltage = analogRead(36) / 4096.0 * 6.566 * (vref / 1000.0);
