Software projects typically don't backport significant new features (like support for entirely new C++ standards) into maintenance releases. They are only for bugfixes.

As Jonathan points out, some parts of C++20 are already available in older releases. So if you really want to know you need to say what C++20 features you are actually looking for. I don't know what is in GCC 11. I can say for sure that GCC 12.x, 13.x, and 14.x set __cplusplus to 202002L.
