The menus are a little complicated as there are multiple settings associated with how bracketing behaves. The Bracketing Menu settings should appear in the C.Fn.1 menus. These control exposure and are located under the Orange camera icon to the right, not the red camera icon to the left. For detailed explanation of each setting I must refer you to the full User Guide that is available for download from the EOS 80D Support Page.
You could set AEB in the menu (red menu #2) and assign your settings to a Custom Shooting Mode (C1 or C2) on the dial. Then when you need it, use that Custom Shooting Mode. You could also create a My Menu Tab in the green menu and add the AEB setting to that tab for easier access (page 440 in the full manual). Another option is to use the Q button to set AEB.
Have you considered using one of the c1- c3 custom modes? You can set up all the bracketing features and register them as a custom set. (suggest you register the default settings to C1 so you can go back to them if you ever have an issue).
True, I was staring at mine and never noticed! Thanks for that. Still, the principle holds true - the C modes are great for switching to groups of custom settings.
