Windows finds the first and doesn’t bother looking for a second one, which happens to contain grub and my efistubs.
Windows will go ahead and clear the UEFI menu sometimes, but manually booting an efi file and then re-adding the grub and stub boot entries is small compared to having my stuff actually deleted.
That certainly helps.
In my case the solution is two EFI partitions.
