How to cripple Win 10?

Since you want access to Win 10, cripple is not what you want. One sets the boot priorities in bios. Set Win 10 as second so if the bios mistakenly misses 11you can boot to 10 and have an acvtive drive to use to restore the priority you want.

How to cripple Win 10?

You can delete the Windows Boot Manager (EFI) partition (or just the files on the partition by formatting that partition) on the disk in question. The easiest way to do this is with diskpart. Just be sure you're selecting the correct disk.

I don’t want access to Win 10. I don’t trust the BIOS to not flip boot drives for some reason. Killing the boot partition like bba-tcg suggests sounds good.
