Filter for default settings

Hi,
It’s not that easy as the options assignment happens in plugin class constructor.
What you can do however is to detect the PVC activation using this: https://codex.ww.wp.xz.cn/Plugin_API/Action_Reference/activated_plugin
And update the PVC post_views_counter_settings_display option.

It would be something like this, but you have to test it:

/**
 * Hook into activated_plugin action.
 * 
 * @param string $plugin
 */
function custom_pvc_activation_action( $plugin ) {
	// check if PVC constant is defined,use it to get PVC path anc compare to activated plugin
    if( defined( 'POST_VIEWS_COUNTER_PATH' ) && $plugin == plugin_basename( POST_VIEWS_COUNTER_PATH . 'post-views-counter.php' ) ) {
		// get display options
		$display_options = get_option( 'post_views_counter_settings_display' );
		// set position value
		$display_options['position'] = 'manual';
		// update options
		update_option( 'post_views_counter_settings_display', $display_options );
    }
}
add_action( 'activated_plugin', 'custom_pvc_activation_action' );
