First of all, You are now using old generation mode. I recommend change to Generation 3 from Appearance > Customize > Lightning Function Setting. But… Generation 3 don’t have front page widget area that, you have to some changes.
Please take a full backup with tools such as UpdraftPlus plugin before making any changes.
Install and activate plugin VK Block Patterns
Move to the front page ( post ) edit screen
[ + ] -> Patterns -> PR Content -> Column Icons and modify it.
Change to Generation 3 from Appearance > Customize > Lightning Function Setting.

6. Appearancr > Customize > Additional CSS
In case of Generation3 ( all pages )
.vk_posts.next-prev{ display:none; }
In case of Generation3 ( one column only )
.main-section:where(:not(.main-section--col--two)) .vk_posts.next-prev{ display:none; }
In case of Generation2 ( one column only )
.mainSection-col-one .vk_posts.postNextPrev{ display:none; }
In case of Generation2 ( all pages )
.vk_posts.postNextPrev{ display:none; }
edit what is show on the sidebar in the 2 column.
Put the VK Post List widget or VK Taxonomy list widget and so on
