@Yazan Tahhan Apologies for the delay in response and all the inconvenience caused because of the issue.
Below is the input i got from our internal team:
A Batch VM image with 3ds Max 2021 will be available in 1 to 3 months. Work is in progress, but a more precise date is not available yet. A service update will be published when available - Azure updates | Microsoft Azure.
Hope it helps.
