Any custom TLS client that has minor implementation of HTTP with custom cipher suite support?

As we all know, C# is one of the languages that cannot change cipher suites in the http client. I know they added support for it a while back, but it only works on linux. Don't know why they've yet to add a full implementation for it that supports windows. A few years back, I found a library that utilized BouncyCastle.Crypto and had a partial implementation of HTTP. Enough to do basic POST and GET requests with custom cipher suite ordering. Unfortunately, I don't remember the library and was just wondering if anyone knows of any libraries that offer such functionality?...

✅ static, public, void

I'm new to C# and I was wondering if I were correct that static means you can use an object or method outside of the file you are coding in, public means you are able to use an object or a method outside of a specific class and void means you will not return anything in the method proceeded?

How to get documents for specific user by Cloud Firestore?
