Can Forge paid app be private?

I’m looking for the limitation of Forge function (Faas) as the following link:
[https://developer.atlassian.com/platform/forge/platform-quotas-and-limits/#function-as-a-service-quotas](Function as a Service quotas)
It looks like if I need more run time in my app, I have to use paid app.

However, as the defination in the following link, I have to make my app to be public because

Paid apps - Apps listed on the Atlassian Marketplace with a paid license
[https://developer.atlassian.com/platform/forge/platform-quotas-and-limits/#installation-quotas](Installation quotas)

Is there any way to make distributed app(which looks like private) to use the same plan as paid apps?
