### Enable or disable instance-level CI/CD variables **(CORE ONLY)**

Instance-level CI/CD variables is under development but ready for production use.
It is deployed behind a feature flag that is **enabled by default**.

can opt to disable it for your instance.

To disable it:

```ruby

```

To enable it:

```ruby
Feature.enable(:ci_instance_level_variables)
```
