Lock a non-workflow BP for edition

Hello Everyone,

I would like to know if there is a way to lock a record of a non_workflow BP.

For example, I have a record (in Pending status) in a non workflow BP (1) that users can access to make some changes. Then, a validation record of BP with workflow (2) is going to validate this record with a Record Status Pulldown (status of my record 1 change from Pending to Approved). I would like to lock the record 1 even if users where able to modify it before is Approval.

Do you know if we can lock a record from non workflow BP only on its status ? Does Terminal status works this way ?
