Hiding a blog post's publication date for Google search results

Site URL: https://happydrops.nl/

Dates in the SERPs have a bad impact on the click rate. I like to hide the publication date of the blog posts, within the Google search results. 

We use the Brine family (Brasil template) for our website. And it’s the 7.0 platform.

On the summary blocks we made sure to hide the primary and secondary data. So there are no blog dates visible on our website. 

On the Design and Site Styles the settings the blog metadata settings are also for primary and secondary on None

So all the possible settings for hiding the post meta data settings are switched off. 

And yet Google is showing our publication data in the search results as you can see below.

Can anybody help us with hiding the blog post publication date in Squarespace so Google search results doesn’t show them anymore?    

I'm looking for an answer to this too. Did you get any luck on this @BRands?
