Right click on the project node in the solution explorer and then 'Archive for publishing'? – Fourposter

It is not possible directly (or maybe in 2019.3, I haven't updated yet), but as far as producing release version, with consistent / automatically updated build number, zip aligned and signed apk, You can use an extra tool, like for example cake, that could leverage MSBuild and handle all the process of increasing the build number, cleaning / restoring the nugget packages, building/signing/ZipAlignin the apk, running tests, uploading the apk to your server/google.

Here is a example of such a Cake file:

#addin "Cake.AndroidAppManifest"
#addin nuget:?package=Cake.Git
#tool nuget:?package=NUnit.ConsoleRunner&version=3.9.0


var target = Argument("target", "Default");
var configuration = Argument("configuration", "Release");
var SolutionFile = "../MyProject.sln"; 
var projectToBuild = "./MyProject.Droid.csproj";
var buildDir = Directory("./bin") + Directory(configuration);
var objDir = Directory("./obj") + Directory(configuration);

var pkg = "com.organisation.app";
var AndroidSDK = "/Users/Me/Library/Developer/Xamarin/android-sdk-macosx";
var AndroidBuildToolsVersion = "28.0.3";
int rc = 0;

// the build number will be set to the commit number. First commit, bn = 1,...

var buildNumber = GitLog(Directory(".."), int.MaxValue).Count; 

Task("Clean")
    .Does(() =>
{
    CleanDirectory(buildDir);
    CleanDirectories(objDir);
});

Task("Restore")
    .IsDependentOn("Clean")
    .Does(() =>
{
    NuGetRestore(SolutionFile);
});

Task("Increase build number")
    .IsDependentOn("Restore")
    .Does(() =>
{
    var pathToAndroidManifest = "./Properties/AndroidManifest.xml";
    var manifest = DeserializeAppManifest(new FilePath(pathToAndroidManifest));
    manifest.VersionCode = buildNumber;
    SerializeAppManifest(new FilePath(pathToAndroidManifest), manifest);
});

Task("Build")
    .IsDependentOn("Increase build number")
    .Does(() =>
{
    MSBuild("../MyProject.sln", new MSBuildSettings().SetConfiguration(configuration));

    MSBuild(projectToBuild, s => {
        s.SetVerbosity(Verbosity.Quiet);
        s.SetPlatformTarget(PlatformTarget.MSIL);
        s.SetConfiguration(configuration);
        s.WithTarget("SignAndroidPackage");
