libcurl supports run-time introspection of its features where it makes sense:
https://curl.haxx.se/libcurl/c/curl_version_info.html
But in most cases, it should be sufficient to handle error codes that are
returned out of libcurl API in case a requested feature is not supported,
usually CURLE_NOT_BUILT_IN:
https://curl.haxx.se/libcurl/c/libcurl-errors.html#CURLENOTBUILTIN
... which defensively written code should do anyway.
