I ran into the same issue. This snippet worked for me.
add_action('elementor/frontend/after_register_styles',function() {
foreach( [ 'solid', 'regular', 'brands' ] as $style ) {
wp_deregister_style( 'elementor-icons-fa-' . $style );
}
}, 20 );
You may only need the solid and regular dequeued.
add_action('elementor/frontend/after_register_styles',function() {
foreach( [ 'solid', 'regular' ] as $style ) {
wp_deregister_style( 'elementor-icons-fa-' . $style );
}
}, 20 );
