Thanks for the help guys ??
As Joseph said, you can simply hide it with CSS, and while this won’t hide it from search engines, it will do no harm hiding it this way.
The CSS to hide the publish date above the post title on both the blog and individual post pages is as follows:
.excerpt-meta-top,
.entry-meta-top {
display: none;
}
You can copy and paste that into the Custom CSS section in the Customizer. Once added, the dates will disappear.
