How to disable http v2

[Peter Volkov]

Hi.

After we enabled HTTP/2 in nginx some old software started to fail. So we
would like to have HTTP v2 enabled in general but disabled for some
specific IP:PORT. I've tried two listen directives in server block:

    listen IP:443 ssl http2;
    listen IP:1443 ssl;

The problem is that on both ports I see: * ALPN: offers h2. Is it possible
to disable HTTP v2 for specific IP:PORT?

Thanks in advance,
