Why not . Take a look at documentation.
Place your form to template. Add Name, Email and 2 password fields.
Assign Registration and Custom action to your form.
Create your custom action.
add_action( 'bricks/form/custom_action', 'password_matching', 10, 1 );
function password_matching( $form ) {
$form_fields = $form->get_fields();
$form_id = "id"; // your form ID
$password_id = "id"; // your password form field ID
$con_password_id = "id"; // your confirm password form field ID
$ch_form = $form_fields[$form_id];
$ch_password = $form_fields[$password_id];
$ch_con_password = $form_fields[$con_password_id];
// Check if the form id is the one you want
if ( $ch_form !== 'yourFormID' ) {
return;
}
// Check passwords
if ($ch_password !== $ch_con_password) {
// Passwords do not match
wp_die('Passwords do not match. Please try again.');
}
// continue with your code....
of course there is bit more to it but this should give you some starting points
