How do I disable some cipher suites in Webserver Protection?

After running an SSL check for one of our sites, which is served by our UTM, it turned up that we have 3 weak ciphers being supported by the UTM:

TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA _0xc012_ ECDH secp256r1 _eq. 3072 bits RSA_ FS WEAK 112
TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA _0x16_ DH 2048 bits FS WEAK 112
TLS_RSA_WITH_3DES_EDE_CBC_SHA _0xa_ WEAK 112

How do I disable these ciphers?

    RE: "I don't think deleting the policies deletes the underlying ciphers and DH groups."

    The system allows you to roll your own IPSEC policies from the component parts, and the components are fixed lists, so I cannot imagine that the components would be deleted either.  But the policies are what is available for offer to an IPSEC connection, so removing the policy should be sufficient for the PCI complaint, at least for the ones that the system will permit to be removed.

    Some of those hits in the scan were for non-existent combinations in the policies I see here, Doug, e.g., 3DES/SHA/DH-Group-5.
