In my experience (W11 + Fedora on UEFI Thinkpad), I’ve seen it actually get rid of the Fedora entry from the UEFI boot list. Reinstalling GRUB from chroot didn’t fix it, so I used EasyUEFI and manually added the Fedora EFI file to the boot list and that worked.
So it wasn’t simply changing the boot order, it actually nuked Fedora from the UEFI boot list.
A much more simpler method is to just use Streamfab. No need for nVidia, a second PC etc.
