Can I make the page title on my assigned home page an h2

Previously I got some feedback from Google about having 2 h1 headings on my homepage.
My site title is h1 and so I want to make the page title an h2 heading (but just on the home page)
Is it possible to do that without using a headline block?

Previously I used a headline block for the page title by noticed that when in preview there was No Title at the top of the page.
