Dgraph Response Size Threshold

When expanding the depth level of some of our queries, we get a 504 response and the following message appears in the Alpha log:

message": "while running ToJson: estimated response size: 4294967367 is bigger than threshold: 4294967296"

Is there anyway to increase the threshold or is it a hard limit?

Thanks in advance!
