Welcome to the forum.
I can't comment in terms of physical bits for an F54, however there is a writeup of someone completing this upgrade on a BMW F46, which is the same in terms of coding, ECUs, etc. as a Mini F54/F56: DIY Guide: How to upgrade your 6.5 inch screen to 8.8 inch screen for your F45/F46 (BMW 2er Active/Gran Tourer)
I use E-Sys rather than Bimmertech or Carly for coding & programming.
There are download links and instructions here: Coding: (No Request) Latest Software Links
Good luck!
