Hi @Don,
Welcome to Microsoft Q&A!
Do you want to disable the IntelliSense in HTML page?
Please go to Tools > Options > Text Editor > All Languages > General > deselect the “Auto list members” and “Parameter information” options.
Update:
Please go to Tools > Options > Text Editor > HTML > Advanced > change the “Enable Element Tooltips” to False.
Sincerely,
Anna
