Pagespeed Issue. Plugin slowing down website

I noticed that there are two of these 3rd party scripts that affect pagespeed score in the “Defer parsing of JavaScript” tab.
Are both of them needed for verified reviews?
Is there anything you could do for the “defer parsing of javascript”?

Also in the “Leverage browser caching” we have a few scripts

Is it possible to defer the parsing of these scripts?
Any suggestion would be highly appreciated, Thank you
