Thank you for your post!
When it comes to enabling/disabling Accelerated Networking on existing Azure VMs, if your VM was created individually, without an availability set, you only need to stop/deallocate the individual VM to enable Accelerated Networking. If your VM was created within an availability set, or VMSS, all VMs contained in the availability set or VMSS will need to be stopped/deallocated before enabling Accelerated Networking on any of the NICs.

If you have any other questions, please let me know.
Thank you for your time and patience throughout this issue.
