For the rare occasion that I need Windows bare metal, I have a Windows 11 installation on a usb ssd originally installed via the Rufus Windows-To-Go option that I can just plug into the system and boot off it whenever I need it without it touching my uefi menu or partition on my internal drives. This way I can also use it on another machine if that need arises. Windows can even trim the usb drive it's running on. It pretty much works as if installed internally.
