Can the 1MB request payload limit for an ALB Lambda target be increased?

Question

According to documentation, when using a Lambda target with ALB "The maximum size of the request body that you can send to a Lambda function is 1 MB." https://docs.aws.amazon.com/elasticloadbalancing/latest/application/lambda-functions.html

According to [Lambda documentation](https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-limits.html) the maximum synchronous invocation payload is 6MB.

Is the 1MB maximum request body size for a Lambda target in ALB a hard limit or can it be raised if a customer use case warrants it?

The 1MB max size for the request body cannot be changed.

Also do note the header limits for ALBs which are also hard lmits:

HTTP/1.x headers

Request line: 16 K

Single header: 16 K

Whole header: 64 K

HTTP/2 headers

Request line: 8 K

Single header: 8 K

Whole header: 64 K
