I can use only G Suit SMTP mail server due to company security policy.

I want to configuring 3rd-party SMTP service for using G Suit mail service but I can't set "smtp smtp_password" config in AIRFLOW CONFIGURATION OVERRIDES tap of Cloud Composer.

GCP Guides says "smtp smtp_password The default SMTP password for Airflow. You cannot configure a new password."

GCP Cloud Composer 3rd-party Email Setting guide

Is there any method to set smtp_password in Cloud Composer config? Or any other method of setting G suite mail server for using email sending on DAG?

You cannot set the smtp_password value, as is shown on the page you took the screenshot from. You must use the default password given.

Using a third-party SMTP service requires using the default, publicly known Airflow smtp_password. Cloud Composer does not support configuring the smtp_password because the value is stored in plain text in airflow.cfg and considered unsecure. Use this option only if the connection between the Airflow web server and the SMTP server is secure.

For anyone who wants to look at the page the screengrab was taken from:
