Yes. The icons that appear here are from the DashIcons library. There is a field within the Plugin settings that allows for the icon to be changed by selecting the CSS class of a different icon from the library.
Go to https://developer.wordpress.org/resource/dashicons and search for an icon that you would rather use. Copy the class given and place this into the field in the PeepSo Downloads Manager configuration settings (Peepso → Configuration → CM Download Manager → Profile Widget).
To learn more about changing the DashIcons see this Help article.
