Is there a way to turn it off?
Only by adding some css to the admin template stylesheet, eg:
.ui-jce .control-group .description {
display: none;
}
I do understand that you want it on by default to help reduce your support time.
Not at all. Joomla 4 includes all form field descriptions inline, so this change just anticipates that. Also, I'm pretty sure most users didn't even realise that a tooltip description was available for each field, so this does help some to understand the parameters better.
