Set profile attributes to NULL with partial update

Hello, when I do a partial update (https://developer.okta.com/docs/reference/api/users/#update-profile-with-id) and set a profile attribute to NULL, the attribute is deleted. Is there a way to keep it and set it to NULL?

I’m expecting it to be NULL because when I create an user and send NULL profile attributes, they are NULL on the user profile. So the two behaviors are not synchronized.
