Any way for users to allocate additional resources for an app?

Hello,
I'm developing an app which heavily relies on background uploads (via URLSession's uploadTask).
The idea is that a user can put the app in the background as soon as the files are written to disk and the upload task is queued.
But the issue I'm encountering is that sometimes a lot of time can pass before the upload actually starts - over 12h in some cases (granted this happens more when upload files are larger than 150MB).
So, is there any way for users to indicate that this app should be allowed to use the resources more than usual?
Is this in a URLSession background session?

I guess. I'm doing it from Flutter and using this library.

I’m going to recommend that you watch WWDC 2020 Session 10063 Background execution demystified (due on Fri, alas) and then come back with your follow-up questions.
