Default to TLS v1.2 in all TLS libraries in 20.04 LTS

OpenSSL set Cipher String to lower seclevel from 2 to 1, like so: DEFAULT@SECLEVEL=1

Can this be done systemwide? I made an attempt but didn’t get anywhere.

I’m really tearing my hair out about this for months now, I can’t find the solution anywhere (and the people who may know probably have no interest in TLS 1.0 & 1.1 anymore — but I can’t avoid it.
