Can you change or restrict certain TLS Ciphers?

Product Name: AltaLink C8130 / C8135 / C8145 / C8155 / C8170 Color Multifunction Printer
Operating System: Not Specified

My customer has a ALC8155 and would like to disable certain TLS ciphers.  The security guide only states that it supports the following, but he only wants to allow ECDHE.  There used to be a way to change SSL ciphers on older equipment.  

Is there a way or not a way to do this?

* TLS_RSA_WITH_AES_128_CBC_SHA256
• TLS_RSA_WITH_AES_256_CBC_SHA256
• TLS_DHE_RSA_WITH_AES_128_CBC_SHA256
• TLS_DHE_RSA_WITH_AES_256_CBC_SHA256
• TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
• TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384
• TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
• TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
• TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
• TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
• TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256
• TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384

Not to my knowledge. I remembered something I handled not too long ago but when I looked it up it was a feature key to enable ECDHE ciphers on the VersaLink line only.

I checked 8100 spar notes to see if there was any SFR comments but no luck.

Thank you for confirming.  I think their only solution is this:
