Can’t seem to hide the HUD tooltip. I don’t use any addons atm other than Immersion, and Details, but yet when I uncheck HUD Tooltip in the edit menu, it only hides the blue box there, but not once out of edit mode. Tips still pop up on mouseover.
Checking/unchecking boxes in edit mode just means you’re editing them or not, it’s not an option to hide them. I don’t believe you can hide the tooltip on default UI without running a script on every login.
