Can't disable "Scotch bonnet" search button -

Hello, My experience with Firefox has been great for more than 15 years. However recently there's been a trend of adding new functionality without asking the user whether they want it or not. Moreover, some things cannot be disabled even if I try hard enough. It was an unpleasant surprise to discover that "This time, search with" panel was removed without my consent, and is now replaced by an extremely inconvenient button. I firmly believe that this is not how UX design is done, and whoever made that choice needs to reevaluate their decision. How can I revert this change besides rolling back the browser version? The setting "browser.urlbar.scotchBonnet.enableOverride" did not help, it reverts to *true* on every restart. I have not been able to find any other settings, and I believe that this is not something that a user should do their research on. Is there a way to affect this change?
