Web.Headers using MS Graph to handle (expected) HTTP-errors seems not possible. Any suggestions?

I have a loop to import Graph datasets from different 365 tenants, like a list of all users for all tenants. Because not all tenants support the same data, some response with HTTP-error. I would like to ignore those errors and continue with the loop for retrieving data of the other tenants. That keeps me from administrating which GET-connectors I shouldn't address for certain tenants (I hope you understand my poor english 🙂

So again, the question is how to handle (and skip) HTTP-errors from Power Query using Microsoft Graph.
