SenseCAP Wireless CO2 Sensor high CO2 levels

I am looking at the SenseCAP Wireless CO2 Sensor for the following application. I have an indoor space where the CO2 limits are constantly between 6,000 - 12,000 ppm, this sensor looks as though it can measure that range OK.

Is it OK for constant operation in this environment, and can I disable any automatic CO2 calibration [does it have this feature?]

12000 ppm should not be a problem. But did not find anything regarding the calibration in the user manual.
