How to set an EWM project to READ-ONLY mode without modifying permissions?

Description:

We are looking for a way to set an IBM EWM project area to a read-only state after project closure or migration (e.g., to Jira).

The goal is to:

- Prevent any further modifications (work items, plans, etc.)

- Keep the project accessible for reference (read-only)

Constraints:

- Do NOT want to modify or revoke user permissions (managed externally via oneIDM)

- Project may use process sharing (template -> child projects)

- Need to avoid impacting other projects

Questions:

- Is there any built-in or recommended approach in EWM to enforce a read-only state without changing permissions?

- Can this be achieved via process configuration (e.g., workflows, operation behavior)?

- Are there best practices for "freezing" a project in EWM in such scenarios?
