AssistContentPolicy management type availability

I’m trying to determine whether the https://developers.google.com/android/management/reference/rest/v1/enterprises.policies#assistcontentpolicy
is available for BYOD devices?

I’m unable to determine what management types it’s available for, usually most settings state they are only available for Corporate Owned work profile devices or fully managed devices  for example. I’m trying to get support from Microsoft (Who are insistent it’s not available for BYOD) to ensure this is available for BYOD devices as we currently have an issue where privileged apps (Assistant apps i.e. Gemini) can grab the screen content from a work profile device.

Thanks for your help!
