Hiding specific text

Site URL: https://corn-apricot-zn88.squarespace.com/

I am trying to hide specific "read more" text on my summary block on my "people page"

I have it all turned on in the display settings and then wrote CSS to  turn it off. And then I tried to target the specific BLOCK to turn it back on. Basically, I only want it to show and click through on 10 or so of the 70 people shown. 

It is either all on or all off, but it seems like I should be able to target text block and change this.
