Specify compression method (zstd) when building (during up command) from compose file

[sevetseh28]

Hi, I wanted to ask if there's a way to override the compression method when building a dev container image using devcontainer up and NOT devcontainer build. I checked the spec but it's not supporting this under the build property. But maybe I missed something. I saw this is supported in the build command. But the build command in turn does not support --override-config which im using.

Also, when I try to use --output during build command I get: --output not supported

Thank you!
