How to allowlist a domain that is getting flagged as malicious via graph API?

We have a number of domains that get blocked by Microsoft Defender as "malicious". We want to allowlist those domains for all users in a tenant via the graph API, but it is unclear how we can do that.

I have looked at this: https://learn.microsoft.com/en-us/graph/api/resources/security-emailthreatsubmission?view=graph-rest-beta but it seems like an odd way to achieving the goal, and it is not exactly clear that it works for what I want.

Can someone point me in the right direction on this? If I have a given domain, https://example.com, that I want to ensure does not get flagged as malicious by Microsoft on a given tenant, how can I achieve that via the graph API?
