Add Search Icon to Search Box

Hi,

Is it possible to add the "fa fa-search" icon before "Search keyword or location" in the following:

add_filter( 'generate_navigation_search_output', function() {
printf(
'<form method="get" class="search-form navigation-search" action="%1$s">
<input type="search" placeholder="Search keyword or location" class="search-field" value="%2$s" name="s" title="%3$s" />
</form>',
esc_url( home_url( '/' ) ),
esc_attr( get_search_query() ),
esc_attr_x( 'Search', 'label', 'generatepress' )
);
} );

Also, is it possible to disable the hover text option on the mobile navigation menu so that the items don't change color (inherit hover color from desktop) when clicked.

Thanks
