CloudBuild non ephemeral worker for Bazel

[yerinu2019]

As a monorepo size using Bazel becomes bigger, Cloud Build non ephemeral worker becomes slower to download and initialize Bazel toolchains and third party Bazel rules. Bazel remote cache and execution do not help to reduce this time and cost. It takes Bazel build and test 10 times longer than local Bazel Build.in CloudBuild.

Is there any way to use non ephemeral worker machine pool for Bazel build?

Thanks.
