Does Elastic Load Balancing service limit traffic based on payload size?

I would like to implement an upload API to handle large files (i.e. 1GB+). The architecture that I have in mind looks like this (I am intentionally avoiding uploads to S3).

I know that some services like the API Gateway limit request payloads to a maximum of 10MB per request. Does ELB impose a similar limitation that would make the above architecture unworkable?
