Can I override Vercel system environment variables in GitHub Actions?

Vercel’s documentation mentions that only one custom environment variable can be overridden in the Pro plan. However, I need to override system environment variables specifically within my GitHub Actions workflow.

In my deployment setup, Vercel detects the branch and triggers an automatic release.

I know that using custom environment variables allows multiple values to be changed. However, I noticed that the API modifies original_environment and environment values.

Would it be possible to override these values to receive my desired environment configuration? If so, how can I achieve this?

// in preview 
        "original_environment": "Preview – project-name",
        "environment": "Preview – project-name,

in production
        "original_environment": "Production – project-name",
        "environment": "Production – project-name,
