Why does Windows 11 change the UEFI boot order?

I am dual booting a Dell Precision 7520 with Fedora 35 and Windows. Worked fine with Windows 10. "Up"graded to Windows 11 and now every time I boot into W11 it puts its own boot loader ahead of "fedora" in UEFI Setup. So every time after booting into W11, I need to hit F2 and reset the boot order in the UEFI Setup. I've developed a workaround, but it doesn't survive an update to W11's bootmgfw.efi file, nor an update to grub.cfg. Nevertheless, my solution means that I can go for many months without having to do it again. Here is my workaround: 1. boot into Linux 2. Make a backup of the MS Boot directory, just in case:

cd /boot/efi/EFI/Microsoft
cp -a Boot Boot.bak

3. Then do the following,

cd /boot/efi/EFI/Microsoft/Boot
cp -p bootmgfw.efi bootmgf2.efi
cp -p /boot/efi/EFI/fedora/grubx64.efi bootmgfw.efi
cd /boot/efi/EFI/fedora
cp -p grub.cfg grub.cfg.bak

4. Now edit grub.cfg and replace "bootmgfw" with "bootmgf2" (note that the real grub.cfg might be in /boot/grub2 rather than in /boot/efi/EFI/fedora) 5. reboot Now when Windows 11 puts itself top of the list in the boot order, and boots its bootmgfw.efi, it is actually booting grubx64.efi, which loads grub.cfg. As mentioned, you'll have to repeat steps 3 and 4 when bootmgfw.efi and/or grub.cfg are updated. I turned the above into a script which I only have to run once every several months when W11 updates its bootmgfw.efi file. Given the non-permanent nature of the above solution, is there a better solution? Note that after weeks of researching this problem, I came across a solution suggested by "Piotr" a few years ago to reset Windows "{bootmgr}" to \EFI\fedora\grubx64.efi, but that didn't work. Windows had no idea about \EFI\fedora...
