If you want to turn off the Bing logo in edge then you can do that by clicking the 3 dots (top right), click Settings, then sidebars and click discover, and choose to turn OFF Show Discover.
Or if you want to do this on the taskbar you just have to right click on your Taskbar, click News and interests, and then click Uncheck Show highlights.
And then if you mean Bing Ai when you are searching things up on bing.com, then go to the
Bing Website! in a signed in account. Then click the hamburger (three lines) menu at the top right, before clicking "Labs" and then toggle the off button.
Hope it helps de-binging your PC
