Bob answers:

This will help you.
get_term_children( int $term_id, string $taxonomy )
This will Merge all term children into a single array of their IDs.

Then pass that array into your post type tax_query with field "term_id"


Francisco Javier Carazo Gil answers:

Instead of doing this, I would use the hook: pre_get_post.

I would change the default query to include there also the term children into the tax query that is being executed.
