Pico: How to change the I2C timeout when using a i2c id scanner?

When testing this i2c scanner I figured out that there is a delay of 2sec before next scan.
A full scan over the 120 id will take about 240 seconds.

Is there a option to change this delay/timeout?

function getSSMS() {
  return [Date().getSeconds(),Date().getMilliseco­nds()].join(':');
}

function isDeviceOnBus(i2c,id) {
      console.log(getSSMS(),id);
      try {
        return i2c.readFrom(id,1);
      }
      catch(err) {
        return -1;
      }
}

function detect(i2c,first, last) {
      first = first | 0;
      last = last | 0x77;
      var idsOnBus = Array();
      for (var id = first; id <= last; id++) {
        if ( isDeviceOnBus(i2c,id) != -1) {
          idsOnBus.push(id);
        }
      }
      return idsOnBus;
}

SCL = B6; SDA = B7;  // PICO
I2C1.setup({sda:SDA,scl:SCL});

setTimeout(function(){
  console.log('I2C detect as array:',detect(I2C1));
},1000);

// output
