Magento 2.2では、MagestyAppsの回答を得ることができませんでした。いくつかの追加ファイルを追加する必要がありました。なぜなら：
- 支払方法のカート価格ルールが管理者から削除されました（DaFunkyAlexが指摘）。
- Magento 2.2では、メソッド
\Magento\AdvancedSalesRule\Model\Rule\Condition\FilterTextGenerator\Address\PaymentMethod::generateFilterText（実際にはにフォールバックする\Magento\AdvancedSalesRule\Model\Rule\Condition\FilterTextGenerator\Address::generateFilterText）がデータを予期していたため、割引は見積もりに適用されていませんでしたpayment_method見積もりが設定されることを。
- MagestyAppsの回答からコントローラーを変更
payment_methodして見積もりアドレスにデータを設定しても、見積もりが永続化されないため、見積もりが注文になったときには機能しませんでしたpayment_method。
次のモジュールがうまく機能しました（MagestyAppsの回答のおかげで、その上に基づいていました）：
