Environment details

1. Spanner Java lib 6.105
2. OS type and version: Mac OS X 26.2
3. Java version: 25

Steps to reproduce

setBuiltInMetricsEnabled() simply has no effect.
Create the client within a project without time series permission and observe the same result

Code example

This is the only place in the code where SpannerOptions is created.

              var optionsBuilder =
                  SpannerOptions.newBuilder()
                      .setProjectId(config.getInfraProjectId())
                      .setBuiltInMetricsEnabled(false);
