@Ahmed Alshatawi Thanks for posting in our Q&A.
For this issue, there is no built-in setting can configure a reboot every 2 weeks in intune. Maybe you can write a PowerShell script to make it.
Based on my check, this CSP contains some settings that are under development and only applicable for Windows Insider Preview builds. These settings are subject to change and may have dependencies on other features or services in preview.
And in this CSP official article, it shows value in ISO8601
So, based on my search about ISO8601, the value may be "R/2025-W01-1T22:00:00Z/P1W". It means begin from 2025 first Monday, every Monday, 22:00 will repeat this action.
Hope it will help.
