I doubt it, but there is:

    $ openssl genpkey -algorithm ec -pkeyopt ec_paramgen_curve:prime256v1 | openssl ec 
    read EC key
    writing EC key
    -----BEGIN EC PRIVATE KEY-----

    -----END EC PRIVATE KEY-----

There is no correspoding EC-specific PEM public key form in OpenSSL.
You should be using the algorithm agnostic formats.
