Can I set a hard limit on my AWS spend? [duplicate]

Is there a way I can set a limit on my AWS spend? I've tried AWS Budgets and also CloudWatch. but they seem to support only notifications- unless I'm missing something.

Has exceeded 85% of the usage limit for one or more AWS free tier?

AWS Free Tier usage alerts using AWS BudgetsAWS Budgets automatically notifies you over email when you exceed 85 percent of your Free Tier limit for each service. For additional tracking, you can set up AWS Budgets to track your usage to 100 percent of the Free Tier limit for each service.

What is the limit of AWS free tier?

AWS Budgets has a Free Tier limit of 62 budget days per month, so creating a single budget falls within the AWS Free Tier limit. As the name implies, AWS Free Tier-eligible service usage is free.

What happens if your use of an AWS service goes over the free tier threshold?

Q: If I go over the Free Tier limit in a given month, how much will I have to pay? If your usage exceeds the monthly free tier limits, you simply pay standard, pay-as-you-go AWS service rates.

No it is not possible.

You can set only the notifications if forecasting cost exceeds the threshold through AWS budgets / CloudWatch.
