The information you got so far is correct. If you want to keep your x86(-64) install, you'll have to use emulation rather than virtualization, which is painfully slow. Keeping a separate machine for this also seems less than ideal. I'd say bite the bullet and build a fresh VM – D2010 on Windows 11 ARM in Parallels 20 works flawlessly here. The 32-bit limitation only applies to macOS apps. One thing to be aware of, though: if you need to work with certain hardware, the lack of drivers could pose an issue.
