Automatic .csproj editing needs to be added in Godot .NET version.

[Foxchandaisuki]

In Unity engine, we just have to select the build target platform and click build button.

By the way in Godot .NET, we have to manually edit .csproj file, writing code like below to make the C# code AOT-compiled:

<Project Sdk="Godot.NET.Sdk/4.2.0">
  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <EnableDynamicLoading>true</EnableDynamicLoading>
    <!-- Use NativeAOT. -->
    <PublishAOT>true</PublishAOT>
  </PropertyGroup>
  <ItemGroup>
    <!-- Root the assemblies to avoid trimming. -->
    <TrimmerRootAssembly Include="GodotSharp" />
    <TrimmerRootAssembly Include="$(TargetName)" />
  </ItemGroup>
</Project>

I hope that process was not required anymore and Godot become more user-friendly.

Selecting target platform and selecting to do or not to do AOT compile should be supported via Godot editor's internal feature.
