There is a setting in the  BIOS/UEFI  of the  5G  Laptop  whereby we can enable or disable the  Radio to prevent the 5G Laptop from connecting to the 5G Cellular Tower so that 5G high speed broadband is disable and  incoming calls is disable .  This setting can be made incremental  ( 5/10/15/20/30/40  minutes )  or it can be enabled or disabled when required and this setting should be made available in every  5G Laptop , so that we can work on our 5G laptop  with minimum interruption or no interruption at all .  A simple analogy is something like the  " Flight mode "   setting we  have in our smartphone .
