Should I disable TLS 1.0 and TLS 1.1. support and get an A at SSL Labs?

Yes.
And in your case, all of the vhost configs override that default setting with the LE included file.
So it really serves no purpose (in your case).
But who is to say that you won’t in the future add another site and you won’t use certbot to create the TLS vhost config…
So it is difficult to say what is best.
I do know that keeping a good document/notes on what is done / when / and why can make life easier when trouble arises (which it will - sooner or later).
