iOS, Firebase for testing (Free iOS program)

After I add Firebase to Unity, Look like it’s contain dependencies with in-app but I didn’t use one.
I just need for remote config.

After I exported to Xcode it’s failed
“The ‘In-App Purchase’ feature is only available to use enrolled in Apple Developer Program”
Which I don’t have one.

Is there anyway to disable avoid this fail or disable in-app.
Or I just need to enroll iOS program.
