What will be an ideal response?
You can enable the field but lock it in the field properties. That way the user can tab to the field but they cannot make changes to it. When you lock a field, the user can still tab to it but not make any changes to it. When you disable a field, the user cannot tab to the field or make changes to it. If you want the user to be aware of the field and take notice of it, then you could lock it. That way, the user will still tab to the field. If you have an informational field only, like a primary key ID, then disabling would be appropriate.
