Ability to enable High Availability option to MySQL 2nd generation instances


It seems that 2nd generation MySQL instances don’t use replicas anymore and it seems that there is no way at the moment of enabling high availability for MySQL. I found this option https://www.terraform.io/docs/providers/google/r/sql_database_instance.html#availability_type in the docs but is only pointing to Postgres.

For reference from Google docs https://cloud.google.com/sql/docs/mysql/high-availability#legacy_mysql_high_availability_option.

Is there a way to enable it using terraform?
