Problem with Ubuntu 20.04.4 SSL and TLS1.3

SYSTEM INFORMATION
OS type and version Ubuntu 20.04.4
Virtualmin version 7.1-1

Hi I’m not able to disable TLS1.3 and use only TLS1.2 in my openssl configuration

Tried to change openssl.conf and/or apache virtualhost configuration to enable ONLY TLS1.2 but if I chet with ssllabs I get that 1.3 is still enabled.

what I miss?

I cant change SSL configuration of my virtual hosts.

enabling only TLSv1.2

SSLProtocol -all +TLSv1.2

result in www.ssllabs.com: ‘This server supports TLS 1.3.’

Probably I found:

In my configuration I have a vh xx.yy.com
and n vh like
subn.xx.yy.com

but I cant set the apache directive for choose TLS in sub vh

if I set in root vh all the subs gets the directive.

In my environment is not a problem because I want all vh share the same ssh TLS methods, but… WHY??
