[Question] Upload custom TrustStore to accept internal CAs for organizations and enterprises

### Question

For some enterprises and organizations, the SSL issuing organizations are likely to be internally managed, and the internal websites with SSL certificates issued by these organizations also needs to be monitored.

There have been a few issues that have mentioned similar scenarios. #2773

**We may need a feature to upload user-defined TrustStore** (I'd like to be involved in the development if possible) to be compatible with any enterprise or organization's internally-issued certificates.

No file or test is named; start by reading related issue #2773 and locating the Java SSL/trust configuration. Clarify the entry point for supplying a user-defined TrustStore and the expected behavior for internally issued certificates. Done means the feature scope is agreed and certificate acceptance is covered by tests.
