Blog Summary Block Hide Latest Post

This may not be possible but is there a piece of code that can applied which hides the latest blog post on summary blocks? I'm aiming for more page-specific coding, rather than site-wide.

Attach a  category to your blog posts, could all have category 2020, filter the summary to use category 2020, don't give the last post that category and it will not show up in the summary all the rest will. 

The website it about to go live so it will probably be lynnepalmerinc.com/insights-executive-recruitment-blog but if not, it is https://emu-jaguar-5y4h.squarespace.com/insights-executive-recruitment-blog and the password is lp -- that is a lowercase L and lowercase P.

I have been able to hide the first (most recent) post. That is fine. BUT, when I do, there is an empty space showing up in the first row of the summary block. Here are the two codes I have used.

Can you help? For now, I have the code disabled. 

#block-yui_3_17_2_1_1594082530518_15247

.summary-item:nth-child(1) {

  display: none;

}

#block-yui_3_17_2_1_1594082530518_15247
.sqs-active-slide  {
  display:none!important;
}

thank you!!!!
