Resolution

Recommended fix is to upgrade NSX from 4.2.3.1.0-24954727 to 4.2.3.3.0-25171318 via SDDC Manager, There is no workaround available to change the status to isShareable True 

• In SDDC Manager, ensure the NSX 4.2.3.3.0-25171318 upgrade bundle is available in the depot (online depot or downloaded offline bundle).
• Go to Lifecycle Management → Updates/Upgrades, select the management domain, and apply the NSX upgrade to bring NSX from 4.2.3.1.0-24954727 to 4.2.3.3.0-25171318. 
• Verify the NSX cluster shows version 4.2.3.3.0-25171318 and status ACTIVE after the upgrade.
• Re-run Add Workload Domain. The cluster will now report isShareable: True automatically and the operation will proceed.

Additional Information

isShareable is not a configurable setting. It is calculated automatically each time based on the NSX-version-vs-BOM comparison. It cannot be edited, toggled, or set to True manually via the UI, API, or database.
