    Yes; Using CoreRT/NativeAOT, you can produce valid UEFI executables. I worked on a hobby OS last year using CoreRT: https://github.com/Michael-Kelley/RoseOS It's outdated and will need some changes to work with NativeAOT (which has replaced CoreRT), but it should give you an idea of the kind of work that is involved in writing an OS in C#.
