-After you add overrides to an Auto Scaling group using a [mixed instances policy](https://docs.aws.amazon.com/autoscaling/ec2/APIReference/API_MixedInstancesPolicy.html), you can update the overrides with the `UpdateAutoScalingGroup` API call but not delete them. To completely remove the overrides, you must first switch the Auto Scaling group to use a launch template or launch configuration instead of a mixed instances policy. Then, you can add a mixed instances policy again without any overrides.
