The AvailableUpdates registry key and the scheduled task should work the same way as on client machines.
On 2012R2 you will need ESU updates since the July 2025 update is required (and the November 2025 update is recommended to avoid compatibliity issues) and 2012R2 won't receive those without ESU. All the other mentioned server OSes should still be in support so you can have them fully updated without requiring ESU.
What happens when you try to use the AvailableUpdates registry key? Will it jump back to zero or 0x4000, and are there any events logged in system event log?
