After reading documentation, I Found the solution. Below is the code I am using to generate unique id for each form.

/**
 * WPForms, Generating Individual Unique ID for a Form
 *
 * @param array $fields Sanitized entry field values/properties.
 * @param array $entry Original $_POST global.
 * @param array $form_data Form settings/data
 * @return array $fields
 */
function be_wpforms_update_total_field( $fields, $entry, $form_data ) {

	// Only run on my form with ID = 14501
	if( 14501 != $form_data['id'] )
		return $fields;

	// Calculates total entries in a particular form and adds one to it
	$fields[3]['value'] = wpforms()->entry->get_entries( array( 'form_id' => 14501 ), true ) + 1;

	return $fields;
}
add_filter( 'wpforms_process_filter', 'be_wpforms_update_total_field', 10, 3 );
