How do I turn off glossary and/or index button for Responsive HTML5?

I do not want to use a Glossary or Index, only TOC and Search for my help system. Can I turn off the glossary and index buttons with the Responsive HTML5 output?

I deselected those two items in Project Set-up - Windows - main - properties. But that seems to affect Web Help but not Responsive HTML5.

Is there a way to do this?

Thanks.
