SEN0471 and SEN0466

Good morning or afternoon, excuse me, I have a question about the SEN0471 and SEN0466 sensors. Is there any way to make them measure lower values? For example, where we are about to implement an urban air quality system, the average NO2 value for 2024 is approximately 28.56 µg/m³ (0.015 ppm). However, the SEN0471 sensor has a resolution of 0.1 ppm, which is very high for the NO2 levels in the air where I live. Therefore, I don't know if it's advisable to install these sensors, or if there's a way to program them to lower their measurement threshold. Please help me with this question. Thank you very much in advance for your response.
