How to publish net core project to AnyCPU?

Question

I use this command

dotnet publish -c Release --force -r **win-x86** --self-contained true 

try to publish a project, while I want to publish a any cpu project, with

dotnet publish -c Release --force -r **AnyCPU** --self-contained true 
dotnet publish -c Release --force -r **win** --self-contained true 
dotnet publish -c Release --force -r **any** --self-contained true 

said the RID cannot be found.

Is there a way to publish a any cpu project for .net core(.net 5)?
