How to restrict Assessment Result access for a specific student using User Permissions?

I’m working in Frappe Education and need help with restricting access to Assessment Results for a particular student.

Currently, student access is controlled using User Permission on the Student doctype, and the option “Apply to All Linked Document Types” is enabled so they can see only their own records across linked documents.

Since the Student user permission is applied to all linked doctypes, it automatically allows access to Assessment Result as well. I’m unsure of the best way to block only Assessment Result visibility for that particular student while keeping the rest of the permissions intact.
