Well more userfriendly than a whole code – only to copy and paste into the copyright input field?
Ok – glad we had talking about.

Good luck to you.

Can you have a look to Dashboard – Settings – Reading : Search Engine Visibility if there is a mark – a robots text is set to not index the page.

by the way – you can even use it with shrinking header and on my test page: Link
i placed the now the same image in background-position : fixed – nice effect.

if it is only an image ( without content and other dynamic stuff)
you can simply add an image via pseudo-element: ( in my case it is page-id-3041)
the height you choose for that must be in addition to the normal main: padding-top value
(my testpage has a header-height of 130px + 250px = 380px

.page-id-3041  #header_meta:after {
  content: "";
  background-image: url(/wp-content/uploads/macro.jpg);
  background-repeat: no-repeat;
  background-size: cover;
  width: 100vw;
  height: 250px;
  position: relative;
  left: 0;
  bottom: 0;
}

.page-id-3041 #header_meta {
  display: grid;
}

.html_header_top.html_header_sticky #top.page-id-3041 #wrap_all #main {
    padding-top: 380px;
}

since it is part of header_meta, the height has already been taken into account by avia-snippet-sticky-header.js script:
topbar_height = header.find('#header_meta').outerHeight(),

This is still working even with Enfold 4.6. : https://kriesi.at/support/topic/social-bookmarks-widget-how-to/. – do not forget the css code!
If it is too much. there are possibilities to make it manually.

For Masonry Gallery – try this in child-theme functions.php:

if(!function_exists('avia_change_posts_query')){
	function avia_change_posts_query($query, $params){
	    if(!empty($query['orderby']) && $query['orderby'] == 'post__in'){
                   $query['order'] = 'ASC';
                   $query['orderby'] = 'title';
	    }
	    return $query;
	}
add_filter('avia_masonry_entries_query', 'avia_change_posts_query', 10, 2);
}

ASC ( from A to Z )
DESC ( from Z to A )

Even a preview image ( youtube thumbnail ) is against GDPR (DSGVO) – only if you are willing to download those images and present self-hosted is a safe way.
By the way – Borlabs Cookie (vers.2) has that option to show thumbnail by downloading the files to host it yourself.

first try this in quick css:

@media screen and (min-width:768px) { 
  #footer .widget {
    overflow:visible !important;
  }  
  #text-4 div > img {
      position: relative;
      left: calc(50% + 25px);
      overflow: visible !important;
  }
}

But has the disadvantage that on responsive case the sign is inbetween the two blocks.

__________________
Alternative:

another quick and dirty way ( because all your background-color on #footer and #socket are equal) could be to insert the image to the copyright info field:
delete the image from your widget area.

put this to your copyright input field of Enfold Options:

<img class="aligncenter" src="https://www.moneyprodigy.com/wp-content/uploads/2017/01/Certification-for-Footer-transparent.png" alt="" width="300" height="211" /><br>© Copyright - Money Prodigy <a href="/terms">Terms</a> & <a href="/privacy-policy">Privacy Policy</a> [nolink]

Advantage is that in responsive case the sign is under all widgets – just over your copyright info.

may i ask you why you want to change the date?
If it is on reasons of ordering – in blog or masonry etc pp – you don’t need to change the date. you can have the choice to order it differently.

Sorry my mistake that the custom class goes to the container I missed:

 .avia-icon-grid-container.custom-icongrid li:nth-child(1) .icongrid-char:before {
  content: "";
  background-image: url(https://bp.domain.com/wp-content/uploads/2019/08/1-Start.png);
  background-repeat: no-repeat;
  background-size: contain;
  background-position: center;
  width: 50px;
  height: 50px;
  display: inline-block;
  position: relative;
  border-radius: 50%;
}
