Is it possible to maximum number of simultaneous downlods in runtime rather than in Android manifest or info.plist?

I have two different features where I:
1. Download a large number of small files( around >100 files each of size around 500-1000kb). I would like to download 10 files simultaneously so that the user can open those downloaded files immediately. These downloads do not show notifications and user cannot cancel or resume downloads.

2. Download 5-10 large files(>200mb). I would like to download these large files only one at a time as a. H

Since max concurrent connections are set in the AndroidManifest file, I can download only a fixed number of files simultaneously throughout the app.
Is there any way to set max concurrent connections during runtime?
