help request:Is there a way to selectively disable the proxy protocol for stream ports while keeping it enabled globally

Description

Hi,
I'm working with the following configuration:

proxy_protocol:
enable_tcp_pp_to_upstream: true

stream_proxy:
only: false
tcp:
- addr: 25
- addr: 465

My goal is to enable the proxy protocol for most ports, but disable it specifically for port 465.
Is there a way to selectively disable the proxy protocol for stream ports while keeping it enabled globally?
Any guidance would be appreciated!
Thanks in advance.

The current Proxy Protocol configuration is really a global limitation. enable_tcp_pp_to_upstream: true will enable Proxy Protocol for all upstream connections, without fine-grained control for specific ports.

Not supported now. But according to the nginx rules, it should work.
