This Microsoft's documentation page: https://developer.microsoft.com/en-us/graph/docs/concepts/deployments indicates that support for Delta queries against Microsoft Graph API varies across different resources on each national cloud deployment.
I would like to know exactly which deployments support Delta queries against Microsoft Graph API, but I couldn't find any documentation about this.

As you discovered, we don't currently document which clouds support delta query.
If you're willing to do a bit of investigating, I can show you a trick to see not only which clouds support delta query but also which specific endpoints support delta query.
You can send metadata requests to each cloud like https://microsoftgraph.chinacloudapi.cn/v1.0/$metadata or https://graph.microsoft.com/v1.0/$metadata. Note that these requests don't require an access token in the header so you can actually just open these links in your browser.
Search this XML for delta and you'll see our delta function definitions. For example, the following says that the user collection (GET /users) supports delta query.
This one means that groups supports delta query.
