As defined in https://tools.ietf.org/html/rfc7959#section-2.4, clients can specify a preferred block size for the responses from the CoAP server by using the Block2 option on a request.
This size should be configurable in the library.
When used with block-wise requests, the Block2 option should only appear in the last fragment, as defined in https://tools.ietf.org/html/rfc7959#section-2.7
