Modifying Viva Insights via GraphApi or Powershell

Hi, I can use "Viva Insights" to modify my office hours via https://insights.viva.office.com/#/PersonalApp/AppSettings/WorkWeekSettings/

How do I modify the same via GraphApi or PowerShell or some automated means?

We have to modify the properties for over 2000 users and I am looking at an automated way.
