How to force a Powershell Script to run a specific Version

I have both PowerShell 5.1 and PowerShell 7.0 on my computer. How can I enforce a mandatory version (a specific version, not a minimum or maximum version #) of PowerShell for a given script (in this case, PowerShell 7.0)?

another option is to use #Requires statement

#Requires -Version 7.0

here is the reference from Microsoft support

If it's a script being invoked in a PS shell, you could relaunch it if it's not the correct version.

# At beginning of .ps1
if ($PSVersionTable.PSVersion -ne [Version]"5.1") {
  # Re-launch as version 5 if we're not already
  powershell -Version 5.1 -File $MyInvocation.MyCommand.Definition
  exit
}

# Your script code

If the scripts are launched via Task Scheduler, you could just use the full path to the .exe in the "Actions -> Start a program" section, as they have separate install locations.
