How can I force CUPS in RHEL to use only TLS 1.2

Issue

• Our company wants us to force everything to TLS 1.2, denying TLS 1.1, 1.0, and all SSL version on all ports which offer TLS encryption. I didn't find an option on how to force cupsd to 1.2.
• Need a way to disable TLS 1.0, 1.1, SSLv1,2,3 leave only TLS1.2 enabled.

• Nessus scan finds the following vulnerabilities on our CUPSD server.
  Could you, please, advise how to update cupsd configuration to fix them?
