Is there a way to switch PHP version between 7.4 and 8.0 without making changes to Environment Variables?

Question

My current environment is:

1. PHP7.4
2. Windows 10
3. WAMP

I want to work on different projects but both are on different PHP versions. I face a hurdle in changing the environment files. Is there a way to simply change the PHP version from the WAMP server?

Thanks in Advance!
