Sensor SEN0438 - baudrate change

Hello,

I have a simple question: can the transmission speed (BR) be changed in the temperature and humidity sensor (SEN0438 )? The documentation only states "Baud rate: 9600 (default)", If it is the default option then shoud be an option to change it. I would like to ask for information whether this is actually the case or whether 9600 is the only transmission speed option.
