Yes, I do make it with Serverless (I feel uncomfortable without git taking care of all my changes).
Thanks for pointing to this approach. I’ve already had this plugin installed, so I just added to requirements.txt
sagemaker == 2.59.1

It increased my package size from 40mb to 70mb, but so far that’s fine (while it is less than 250mb limit of lambda).
