My guess is ChatGPT just made it all up. 
So as you can see, we aren’t all out of a job yet. 
There’s no concept of “enabling” or “disabling” a Theme Component, you simply add or remove it from a parent theme. EDIT: incorrect, see @Canapin’s post below!
ChatGPT made it all up. got the wrong end point and body.
Using the browsers network tab, I can see that adding a Theme Component to a parent theme called a
PUT /admin/themes/<id>
(id of component)
With payload something like:
parent_theme_ids: [<parent_id>]
I didn’t make that up, I just looked at the Network tab on my browser 
You are welcome
