github - github アクション マトリックス要素を条件付きにする方法

Question

'strategy' = 'matrix' を使用するワークフローと、構築する特定の構成のリストがあります。

ワークフロー YAML へのリンク (以下にも記載)

#
# build-N-test-v2.1-Dev and build-N-test-v2.1-Release are neary
# identical, but a few tests are commented out (to not needlessly stress CI system)
# for v2.1-Dev builds
#
# NOTE: I've tried many tricks - none which seem to work - to get this working on one file with one
# workflow and tests

しかし、ブランチ = v2.1-Release の場合にのみ、一部の構成のみをビルドしたいと思います。つまり、ほとんどの場合、1 つまたは 2 つの構成をビルドするだけで、リリース時にさらに多くの構成をビルドできます。

これは、スクリプト (ワークフロー) のクローンを作成し、いくつかの名前を変更してコメントアウトすることで実現しました。しかし、そのメカニズムが行列要素で機能するならいいと思います。

各ステップに追加できる「if」機能があることを認識していますが、それは無効なステップで大量のジョブを作成します。私が望むのは、if 部分が false と評価されるマトリックス要素ごとに、これらのジョブをまったくスピンアップしないことです。
