Change publish date to last updated/modified date

Hello,

I’m wondering if there’s a way for the theme to display the last updated date of a post rather than the published date?

For example, the page I’ve linked was published on 24 Jan 2021 and I updated it on 1 Jan 2023. I’ve manually stated this new date in the text of the post but I’d like to have the last updated date to be displayed in the SERP on google rather than the published rate.

Is there a way to change this in the theme without a plugin?

Thanks,

Michelle
