Save_config_kwargs from CLI

I am trying to toggle the overwrite feature of SaveConfigCallback from the command line. Is this possible? I’m guessing that this should be done through the save_config_kwargs argument of LightningCLI, so any help to set values in this dict from the command line would also be appreciated.

I’ve attempted the following:
MyLightningCLI --config /path/to/my_config.yaml --trainer.devices=1 --trainer.num_nodes=1 --data.num_workers=10 --save_config_kwargs={‘overwrite’:True}
