Thank you for your question and reaching out. I can understand you are having query\issues related to Event log size.
- Please disable GPO settings -> Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Audit: Shut down system immediately if unable to log security audits
- Start --> Run --> EVENTVWR.MSC --> Right click Security log, go to Properties. Then, you can clear log, increase maximum log size or choose “Overwrite events as needed"
