On Intel era iMac can an Apple update to Mac OS break Boot Camp partiton?

This quote is the worry - and could be what bit me once already: > "In some cases, users have lost the ability to boot Windows due to EFI partition losing Microsoft boot files." And > "macOS updates now embed firmware updates, which primarily reside in > the EFI partition. It has the side effect of removing parts, that > should not be touched." From here Apple Discussions Our scenario is we have Intel iMacs that were all configured to have Boot Camp/Windows partition. Those that have basically never booted into Boot Camp are fully updated to latest Apple security and feature updates for MacOS. Those that *always* boot directly to Windows of course do not. We are trying to determine if it's reasonable or of any benefit to update the windows Macs to a new macOS. Can Mac updates to a Mac listed as iMac: Apple Inc. 1731.140.1.0.0 SMBIOS 3.3 Date: 5/3/2022 do anything on the firmware side or other that will break Boot Camp and render that useless, or worse, brick the iMac?
