Windows 10: Windows 11 Home upgrade to Pro without Home installation

I'm running Windows 11 on Parallels for Mac. I wanted to install Windows 11 Home, but after I tried to add the product key, I discovered the Parallels already installed Windows 11 Pro. I would like to upgrade my Home product for Pro, I have a Home registration key, but don't have it installed anywhere Pro is already installed - is there a way to upgrade?

Windows 11 Pro Upgrade from Windows 10 Pro Edition

No but after it installed the malfunctioning Windows 11 upgrade it was listed as Windows 11 Pro. Microsoft Windows support advised I reinstall Windows 10 Pro and said that Windows 11 is really only meant for new PC's that come with it preinstalled. MSI website doesn't list my 2020 GT76 Titan dt-039 notebook on their Windows 11 upgrade eligibility list so I guess that's why the Windows 11 Pro upgrade failed. I suggest being careful with trying the Windows 11 upgrade despite it stating my notebook was capable of running Windows 11 it was wrong. Luckily I have the original Windows 10 Pro USB Flash drive because the Windows 11 Pro upgrade was so incomplete I had no way of reverting notebook back to Windows 10 without reinstalling from a USB Flash.

1. How many GB it is? when my pc suggested the upgrade yesterday, it said it's about 4GB just want to be sure.
   
2. I'm using a windows 10 pro so if I upgrade, will it upgrade to a windows 11 pro?
