Block auth headers from some trusted proxies

[slevin22]

Hi,
I'm currently setting up SSO for myself and would like to add my family's home assistant instance. Issue is, they already have it exposed via their own reverse proxy. I can add mine to the trusted proxies and configure SSO, but that would leave them vulnerable through their other reverse proxy.

I'd really like a way block auth headers from specific trusted proxies / IPs if possible.

Thank you!
