Multi GPU training on g5.12xlarge

[H3zi]

Hi all,
I wonder if there's a built-in solution in SageMaker to run distributed training on a g5.12xlarge (4xGPUs)?
From what I can see, SMDDP does not support g5.12xlarge instances, so specifying distributed config in the estimator will not work.

I can hack my way using pytorch\accelerate but I wonder why there's no straightforward way to do it with the SM SDK?

Thanks
