Is "StoreKitTestCertificate.cer" needed if my app uses StoreKit 2?

Can I delete the file StoreKitTestCertificate.cer if I have a published app that uses StoreKit 2?

This is how I was using it earlier to do receipt validation but it's no longer in my released app:

#if DEBUG
    let certificate = "StoreKitTestCertificate" 
#else
    let certificate = "AppleIncRootCertificate" 
#endif

Can I safely delete StoreKitTestCertificate.cer in my next version this file without affecting the released app or TestFlight?
