Creating that list of search engines

maisondasilva 

I think you are asking how to turn that off... You need to the use an enterprise policy (GPO) to specify the list of search engines. There is a parameter that will disable this.

https://docs.microsoft.com/en-us/deployedge/microsoft-edge-policies#managedsearchengines

Look at the exmple provided and you will see

{ "allow_search_engine_discovery": true },

which you can set to false.

I am not aware of a method to set it by itself or in the GUI.
