Lichess seems to offer 7-men endgame table access. I understand that some of them are not yet available, so I looked at http://tablebase.lichess.ovh/tables/standard/7/4v3_pawnful/ to check. Yet it seems that the newest tables cannot be queried (the analysis interface says "Unknown"), at the time of writing, KRBNvKQP is one of them. Is that a bug?
