@Vlad Lustenko (Apptimized), Thanks for posting in Q&A.
From your description, I know you want to increase the maximum size of the uploaded file with Microsoft Graph Beta API from 23GB to 30GB as it allowed for a Win32 app in Intune.
After discussing with the Graph support, it is not suggested that you upload a large file using Microsoft Graph Beta API, because it will consume a lot of performance of the background server and may even cause some errors, but if you want to upload a win32 app into Intune, here are links abbot how to upload an app you can refer.

Hope it will help.
