Yes, FOCUS format is available for EA (Enterprise Agreement), and Microsoft Partner Agreement (MPA) as well. The API version 2023-07-01-preview should be used for v2 exports.
This is the doc for the same https://learn.microsoft.com/en-us/rest/api/cost-management/exports/create-or-update?view=rest-cost-management-2023-07-01-preview&tabs=HTTP which is supported for MCA, MPA and EA
