Specify machine type for a single TFX pipeline component in Vertex AI

I'm using TFX to build an AI Pipeline on Vertex AI. I've followed this tutorial to get started, then I adapted the pipeline to my own data which has over 100M rows of time series data. A couple of my components get killed midway because of memory issues, so I'd like to set the memory requirements for these components only. I use KubeflowV2DagRunner to orchestrated and launch the pipeline in Vertex AI with the following code:

runner = tfx.orchestration.experimental.KubeflowV2DagRunner(
    config=tfx.orchestration.experimental.KubeflowV2DagRunnerConfig(
        default_image = 'gcr.io/watch-hop/hop-tfx-covid:0.6.2'
    ),
    output_filename=PIPELINE_DEFINITION_FILE)

_ = runner.run(
    create_pipeline(
        pipeline_name=PIPELINE_NAME,
        pipeline_root=PIPELINE_ROOT,
        data_path=DATA_ROOT, metadata_path=METADATA_PATH))

A similar question has been answered on Stack Overflow, which has led me to a way to set memory requirements in AI Platform, but these configs don't exist anymore in KubeflowV2DagRunnerConfig, so I'm at a dead end.

Any help would be much appreciated.

** EDIT **
We define our components as python functions with the @component decorator, so most of them are custom components. For Training components, I know you can specify the machine type using the tfx.Trainer class as explained in this tutorial, though my question is for custom components that are not doing any training.

Turns out you can't at the moment but according to this issue, this feature is coming.

An alternative solution is to convert your TFX pipeline to a Kubeflow pipeline. Vertex AI pipelines support kubeflow and with these you can set memory and cpu constraints at the component level.

@component // imported from kfp.dsl
def MyComponent(Input[Dataset] input_data):
  // ...

@pipeline // imported from kfp.dsl
def MyPipeline(...):
  component = MyComponent(...)
  component.set_memory_limit('64G') // alternative to set_memory_request(...)
