The only way to reset the tamper status is to manually delete the log files.
This feature can be configured using the Journald FSS Verification component.
The available settings are the following:
Enabled: Allows to completely enable or disable this feature. If not enabled, FSS verification component will not register itself as a Tamper Detection service.
