Reporting on DKIM status across multiple tenants

I work at an MSP and we'd like to find a way to stay on top of our client DKIM status. We can do this one-by-one by logging in and going to the Defender admin center, of course, but that's a manual process. Is there anyway to get reporting for this? We'd like to get: list of domains in a tenant, and what the DKIM status is.

We already have GDAP set up so I can see the clients in Lighthouse from my user work account and don't have to log in with their account to do basic management.

I've looked over the Lighthouse API documentation and found that it's really great but it doesn't have access to DKIM. We could look at MS Graph because I thought it might be slightly better than using a web browser to query info but it doesn't have access to Exchange Online settings. It looks like we won't have these as a route to get info across our clients.
