Plenty of questions on this and most seem to refer to older versions of Windows and/or Edge.
Using Windows 11 and Edge Version 107.0.1418.42 (Official build) (64-bit), both up to date.
As soon as I attempt to type in the search bar, a "Trending now" drop-down appears.
I've got everything turned off that anyone has ever suggested but I can't get rid of it as shown below.
