You can calibrate it if you can get code running on the chip fast enough
to take a measurement before the temperature significantly changes.

The error is mostly just an offset. There is very little non-linear error.
One or two data points should do. You can use room temperature,
refrigerated, and/or sauna temperature.

Unfortunately for you, getting code to run quickly is not an easy task.
You need to modify the firmware.
