TLS1.0 on remote connection

Plex Media Server Remote Access

Server Version#:newest
Player Version#:newest

I want to disable TLS1.0 on my installation.
I have no old devices (I think & hope) that only support TLS1.0
Does anybody know how? It’s not (only) on the server level. It looks like a setting in Plex as well.

Feedback from an nmap scan:

Anybody? Pretty please?

Dropping a note to track. I am also concerned as the system is accepting both TLSv1.0 and TLSv1 and v2 with weak cipher strengths and known insecure ciphers.

If you want to disable secure connections the option is in Server Settings>Network

ah. sorry. I believe it is there because some older devices, some Smart TV sets if i recall, only supported that, but have let folks know. We might not support those older sets anymore anyway.
