Hello,
Thank you for posting in Q&A forum.
If you use a flexible uniform scaleset, adding these machines to the existing maintenance configuration is sufficient to patch the virtual machines in these flexible scalesets. By adding these virtual machines to the maintenance configuration, the system will automatically schedule maintenance tasks for these virtual machines to ensure they receive timely patches and updates. This can simplify management and ensure the security and stability of the system. I hope this answer is helpful to you! If you have any other questions, please feel free to let me know.
Best regards,
Jill Zhou
