Docker Alternatives for SAM CLI

Hi, does anyone know of any good Docker alternatives (that use the Docker runtime) for Windows to use with the SAM CLI for local development / testing?

I'm asking this based on the note in the SAM CLI installation page (https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-install-windows.html) which I've pasted below:

Note We officially support Docker Desktop but, starting with SAM CLI version 1.47.0, you can use alternatives as long as they use the Docker runtime.

I'm fairly new to AWS and am a total beginner with Serverless.

Thanks
