Is it possible to limit LOVs for assignment status by role?

Summary:

Our HR teams are inquiring if we can restrict line managers from selecting particular assignment status options during a transaction. I found an older post that we can't restrict assignment LOVs by action, but wondering if anyone has done it by security role or another way?

For example, we have a Severance assignment status as one of our termination statuses however only HR professionals should place an assignment in this status because we require a signed agreement first. Right now, if a line manager submits a termination they are selecting the severance assignment status. They route to HR for approval, which if caught the HR team will edit but we are trying to be more proactive about preventing it if possible.
