Well, the example you used uses ClassMethod, which is like an any static method in other languages, and can be called directly with no issues. So, this definitely will work

ClassMethod AnotherMethod()
{
  do ##class(MyClass).Foo()
}

If you would want to do the same, but using instance methods, it can be done as well

Assuming the super class, like this

Class dc.MyClass Extends %RegisteredObject
{

Property Value As %String;

Method Foo()
{
  Write !,"MyClass:Foo - ", ..Value
}

}

and child class

Class dc.SubClass Extends MyClass
{

Method Foo()
{
  Write !,"SubClass:Foo - ", ..Value
}

ClassMethod AnotherClassMethod()
{
  set obj = ..%New()
  set obj.Value = "demo"

  Do obj.Foo()
  
  Write !,"-----"
  Do ##class(dc.MyClass)obj.Foo()

  Write !,"-----"
  Do obj.AnotherMethod()
}

Method AnotherMethod()
{
  Do ##class(dc.MyClass)$this.Foo()
}

}

The output will be this

USER>do ##class(dc.SubClass).AnotherClassMethod() 
SubClass:Foo - demo
-----
MyClass:Foo - demo
-----
MyClass:Foo - demo

And as you can see, the last two calls are working from a super class, and it keeps access to the object

Instead of doing it this way, you can make it even with less code, using Python Embedded

import iris

status = iris.cls('%SYSTEM.OBJ').Load("Production.cls","ck")

# It could be just like this, but OBJ not there 
# https://github.com/intersystems-community/embedded-python-bugreports/issues/2
# iris.system.OBJ.Load("Production.cls","ck")

While we have multiple architectures, it makes now it quite tricky to make IRIS for both x64 and arm64

You can look at this example, where we build IRIS Community with ZPM

IRIS ARM64 does not work in emulated arm64, so, when you use some CI, which supports only x64 and offers qemu emulation to run ARM64 it will probably not work

So, you may try do not start iris inside ARM64 builder, but just add some binires required

Check this template https://github.com/intersystems-community/iris-fhir-template/blob/master...

// Configure FHIR Service instance to accept unauthenticated requests
 set strategy = ##class(HS.FHIRServer.API.InteractionsStrategy).GetStrategyForEndpoint(appKey)
 set config = strategy.GetServiceConfigData()
 set config.DebugMode = 4
 do strategy.SaveServiceConfigData(config)
