how to specify the context location and embedding for an http response

good afternoon;

an http request for json-ld permits the media type profile to specify the ( compacted / expanded / flattened ) aspect of the response document json-ld form.

is there some analogous location for a request to specify the encoding context and/or whether to include the context in-line in the response?

best regards, from berlin,
