Description:
It is recommended that, 'user options' database flag for Cloud SQL SQL Server instance should not be configured.
Rationale:
The 'user options' option specifies global defaults for all users. A list of default query processing options is established for the duration of a user's work session. The user options option allows you to change the default values of the SET options (if the server's default settings are not appropriate).
A user can override these defaults by using the SET statement. You can configure user options dynamically for new logins. After you change the setting of user options, new login sessions use the new setting; current login sessions are not affected. This recommendation is applicable to SQL Server database instances.
Setting custom flags via command line on certain instances will cause all omitted flags to be reset to defaults. This may cause you to lose custom flags and could result in unforeseen complications or instance restarts. Because of this, it is recommended you apply these flags changes during a period of low usage.

From Google Cloud CLI
gcloud sql instances list
1.Clearing all flags to their default value
gcloud sql instances patch --clear-database-flags
OR
2. To clear only 'user options' database flag, configure the database flag by overriding the 'user options'. Exclude 'user options' flag and its value, and keep all other flags you want to configure.
gcloud sql instances patch --database-flags [FLAG1=VALUE1,FLAG2=VALUE2]
Note :
This command will overwrite all database flags previously set. To keep those and add new ones, include the values for all flags you want set on the instance; any flag not specifically included is set to its default value. For flags that do not take a value, specify the flag name followed by an equals sign ("=").
