Question about MH-Z19B

[ManS-H]

Question about MH-Z19B, is there a setting to switch between the following options?
1000 ppm range, 2000 ppm range, 3000 ppm range and 5000 ppm range.

I see when I use firmware ESP_Easy_mega_20210114_normal_ESP8266_4M1M that the range is max 2000 ppm.
And make a new version is for me a bridge to far.

There are some commands available for switching the range.
ESPeasy had them before, but I disabled them as it is a very effective way of destroying your factory calibration data.
ESPEasy does not limit the range to 2000 ppm, it is the sensor you've got which is set to some range.

On older builds it was present.
In this commit it was still present:
https://github.com/letscontrolit/ESPEasy/pull/921/files
So any build shortly after 22 Feb 2018
