How to make an Organization controlled item attribute mandatory at Organization level

Content

We have a requirement to make an Organization controlled item attribute mandatory at Organization level. Default buyers are controlled at inventory organization level, and we have to make it mandatory for just one organization. Via page personalization, we can not specify the Organization, and it will become mandatory for all organizations. So i'm reaching out to this community to see if there are other options available to achieve this?
