Pretty sure there isn't, otherwise FAANG would enforce it top down. They already enforce other practices top down like hiring etc, so if they had data saying that mandating Scrum would make the company X% more efficient they would absolutely do it.
It might be a force multiplier in other types of companies, but it probably isn't in FAANG style companies. Similar to how FAANG hiring can make sense to them but still be bad for typical companies.
