Publish a Windows Application Package Project via command line - visual-studio

Question

How can I publish the UWP package via command line?
I have a WPF application that is packaged with a Windows Application Package Project that ends up being published to the Microsoft Store.
In order to be accepted in the Store, the WPF project needs to be compiled with a preprocessor directive (that I named as "UWP"), deactivating stuff that are not allowed for Store apps.
I'm in the process of migrating the WPF app from .NET Framework 4.8 to .NET 5 and along with that I'm trying to streamline my publishing process via command line.
Is there any way to configure or update the package to support ARM64?
The app will be published outside the Store as x86, x64 and ARM64 and I intend to do the same for the Store version.
When checking the WAPP, I noticed that ARM64 is not available on the list. As you can see in the screenshot, I was able to create a ARM64 build profile, but the architecture is not available on the table.
What have I tried? (Command line issue)
I tried running this command:
MSBuild.exe C:\Project-UWP\Project.UWP\Project.UWP.wapproj /p:DefineConstants=UWP /p:Configuration=Release;AppxBundle=Always;AppxBundlePlatforms="x86|x64|ARM64" /p:OutDir="..\Publish\UWP"
But got these errors:

Notice that there are warnings related to framework references:

This project may not be fully compatible with your project. Microsoft.Common.CurrentVersion.targets 1719
The WPF project was set to use .NET 5, so I don't see why there's any reference to .NETCoreApp 6 or .NET Framework 4.5.1.
What have I tried? (Missing ARM64 issue)
I created a WAPP from scratch and saw that the option for ARM64 appeared in the architecture table.
But when publishing manually via the context menu, I'll get this error:
The specified RuntimeIdentifier 'win-ARM64' is not recognized.
