Anti tampering features to protect Splunk logs themselves?

Path Finder

Does Splunk provide measures protecting against / detecting the tampering of the Splunk logs/data?
The only thing I could find are the hash values for integrity:
https://docs.splunk.com/Documentation/Splunk/8.0.1/Security/Dataintegritycontrol

For example, a malicious administrator could add, change, remove or reorder events afterwards.
I search for techniques related to tamper-evident logging like forward integrity (by key evolution), hash chains, Merkle tree and linking hash values to public media (blockchain, ...).

The Data Integrity feature is all Splunk offers to detect tampering with data. Note that Splunk logs are also indexed and, therefore, protected by Data Integrity.
