How to run a process as non-admin from an elevated PowerShell console?

Maybe there is a way to do it with Start-Process cmdlet that I cannot find? The other related Q/A's I found on StackOverflow such as this, this and this all give a solution to do this with a custom C# code. My question is specifically, is there any straightforward way to do this in PowerShell? i.e. you are in an elevated PS console and want to run a process as non-admin.
