I run Windows 10 quite a bit on my iMac for professional reasons (and sharper small fonts), and the M1 Mac’s lack of Boot Camp support seemed to be a non-starter for me. I did a search already, but the other questions I've found on this topic are 1) about windows 7 and 2) just suggest using WinClone or similar. Installed windows 10 via bootcamp on my MBP running macOS Sierra, but I'd like to expand the Windows partition and shrink the macOS partition, avoiding a reinstall if possible.
