Yes, but not under that name.

For example (constrained also to RSA and ECDHE to keep the list short):

  $ openssl ciphers -v 'AES128+aRSA+kECDHE:!AESGCM'
  ECDHE-RSA-AES128-SHA256 TLSv1.2 Kx=ECDH Au=RSA Enc=AES(128) Mac=SHA256
  ECDHE-RSA-AES128-SHA TLSv1 Kx=ECDH Au=RSA Enc=AES(128) Mac=SHA1

There isn't a cipherlist property that specifically selects CBC, so to
get *only* CBC, you need to exclude AESGCM (and perhaps also AESCCM).
