Once your Debian installation is finished, put this in /etc/default/grub:
GRUB_DISABLE_OS_PROBER=true

Then run
  update-grub
to remove the unwanted entries from your grub menu.

The Grub info documentation describes it as follows:
'GRUB_DISABLE_OS_PROBER'
     Normally, 'grub-mkconfig' will try to use the external 'os-prober'
     program, if installed, to discover other operating systems
     installed on the same system and generate appropriate menu entries
     for them.  Set this option to 'true' to disable this.

Disconnecting disks while installing Debian can help avoid mistakes.
However, it does not permanently suppress the boot menu entries referring to
other OS installations.
