How should we use snapshot test for complex React component

How should we use snapshot test for complex React component?
For example,
I have a detail view page, which contains a lot of small component.
As recommended by Jest, we may be better to use rule 'no-large-snapshot'.
If we write all snapshot tests for each small components, we could keep 'no-large-snapshot'.
However, I want to ensure one thing that when someone modifies a small component, my main detail page will not be changed. (There's several detail page. Maybe page A B are changed but I want to ensure C is not.)
Therefore, I need to snapshot 'detail' page, which will be a large snapshot test file, because it will render all of its children.
