Error: ALTS creds ignored. Not running on GCP and untrusted ALTS is not enabled.

Seen several times whenever the google creds are used to authorize (meaning every time a query is run to vertex ai / gemini:

Doesn't seem to cause unwanted behavior, and this reddit post has a comment saying:

This behavior is caused by a new log message introduced in grpcio version 1.75.0. You can find the specific change in [this commit on GitHub](https://github.com/grpc/grpc/commit/91700c036d920ecf271632710f87f607f339693d#diff-19356ee4274828b67c23eb6293909d2c98513279f53acc01386fe5f06e87326fR93).

Interestingly, the log was implemented with an "error" severity level, even though its content may not indicate a critical failure.

You can suppress this log message by setting the GRPC_VERBOSITY environment variable to NONE.

GRPC_VERBOSITY=NONE

Recommend setting this env var to suppress the error.

Start by locating the environment or configuration used when Google credentials authorize Vertex AI/Gemini queries, then verify how grpcio logging is configured. Done means the unwanted ALTS message no longer appears during those queries without changing their behavior.
