Avalonia offers an unoffical Linux backend for MAUI and there are some other less-maintained backends. I have tried neither of them (I really should) but they might work.
The nice thing about WPF, MAUI, Avalonia and Uno is that they are all extremely similar in concept to the point where you can sometimes just take an existing UI, change some namespaces and class names and get mostly what you want. (WinForms on the other hand is very different from all of them)
