I'd like to automatically disable WiFi when I connect to Ethernet. Some wireless drivers have an option "Disable upon wireless connect". (See for example Automatically Turn OFF WiFi When Ethernet Cable Is Connected to PC.) But on my Dell Inspiron 15 2-in-1 I didn't find this option.

Is there something I can do to get this option? 

(There is this work-around How to Disable a Wireless Network Connection When a Wired Connection is Detected, but it's less convenient.)
