Closing PR because you can just set the following to achieve the same effect:

default['chef_client']['config']['data_collector.server_url'] = 'https://my.automate.server/data-collector/v0/'
default['chef_client']['config']['data_collector.token'] = '93a49a4f2482c64126f7b6015e6b0f30284287ee4054ff8807fb63d9cbd1c506'```
