On the SmartView tab, you can untick "Auto Set QNH" to stop the weather requests.  I wouldn't recommend it, as you will then need to regularly check and set the barometric pressure in your area to set the QNH.

Hi Tarbat, many thanks for the info, please excuse my ignorance, what is the connection of barometric pressure? Is it connected to the flight data we receive?
Many thanks Steve

QNH is used to set the correct altitude above sea level for aircraft below the transition height you've set in Preferences.  If you don't set the correct QNH, then aircraft below the transition height will display with the wrong altitude.

Also explained further on pages 37 and 60 of the user manual.
