Not really, now. I took a shot at it starting with an openssh-8.1p1
building setup over at https://github.com/nkadel/openssh-8.1p1-srpm .
But there are too many library dependency updates to reasonably port
it to CentOS 7. Try CentOS 8 if you feel the need.

You can now build OpenSSH with few dependencies ("./configure
--without-openssl --without-zlib").
The down side is that you end up with limited crypto options (eg only
AES and chacha20 ciphers, only ed25519 keys) and no compression but it
should be otherwise fully functional. Depending on your use case this
may or may not be useful.

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
