How to set environment vars permanently with a shell script in Windows - windows

Question

I have a .bat I use to set some environment vars before running a few programs.
I'd like to permanently set these environment vars, but I don't want to do it manually if possible. Is there a shortcut here? Is there any flag I can set to permanently add to PATH ?
The code is from setupvars.bat made available with OpenVino :
set ROOT=%~dp0
call :GetFullPath "%ROOT%\.." ROOT
set SCRIPT_NAME=%~nx0
set "INTEL_OPENVINO_DIR=%ROOT%"
set "INTEL_CVSDK_DIR=%INTEL_OPENVINO_DIR%"
where /q libmmd.dll || echo Warning: libmmd.dll couldn't be found in %%PATH%%. Please check if the redistributable package for Intel(R) C++ Compiler is installed and the library path is added to the PATH environment variable. System reboot can be required to update the system environment.

For OpenVINO, you need to run the setupvars.sh script every time you open a command line. However, you can also add all the variables needed to your systems environment variables.
On your Windows® 10 system, go to Control Panel > System and Security > System > Advanced System Settings > Environment Variables.
See this document for a list of required variables and their values.
