[sameerz]

Is your feature request related to a problem? Please describe. Drop support for CentOS7, as it will be end of life mid-2024, per https://www.redhat.com/en/topics/linux/centos-linux-eol

Describe the solution you'd like Support for Rocky 8, Ubuntu 20.04, 22.04 will continue

Describe alternatives you've considered RAPIDS is dropping support per https://docs.rapids.ai/notices/rsn0037/ , so I am not sure there are many alternatives
