Yeah it looks like about 1500 grants:

But if the concern is about the provision allowing NSF to claw back funds that have been spent by the organization then the question remains: has that happened? Right now if you search for terms related to NSF clawbacks, most of the top results refer to the PSF's statement or forum discussions about it (like this one). I can't find any instances of a federal clawback related to DEI. If that had happened I would assume that the response from the awardee would have been noisy.
