This option is already available under Preferences, General, Privacy settings so please remove the “IMPROVE TOPAZ PHOTO AI” from export settings. It is so distracting and annoying to see this every time I save/export images.
Hello @nita74-1614 
Just to let you know that this was implemented and that the Share to Topaz option has completely been removed in our Photo AI 3 versions.
Have a great day!
