how do I enable buildkit when building a Dockerfile that needs it?

[lastrafda]

I'm trying to build a Dockerfile using the aws-cdk-lib/aws-ecs lib and then add it to a taskDefinition

    const asset = ecs.ContainerImage.fromAsset(path.join('..'), {
      buildArgs: {
        DOCKER_BUILDKIT: '1',
        NODE_ENV: isProd ? 'production' : 'development',
      },
      platform: cdk.aws_ecr_assets.Platform.LINUX_ARM64,
    })

since my Dockerfile uses the --mount command I need to have BuildKit enabled but I'm getting the following error

[100%] fail: docker build --build-arg DOCKER_BUILDKIT=1 --build-arg NODE_ENV=development --build-arg DOCKER_CLI_EXPERIMENTAL=enabled --tag cdkasset-952c5160f497ac5070d3992a57f00667797897a6aaaee1d5805e17bb448e3529 --platform linux/arm64 . exited with error code 1: the --mount option requires BuildKit. Refer to https://docs.docker.com/go/buildkit/ to learn how to build images with BuildKit enabled

Do someone knows how can I fix this? I'm really lost on this one
