It won't be enough.
Secure boot is associated with native (U)EFI boot mode, whereas "install
grub with MBR" means that grub-pc was installed and must be booted in
BIOS/CSM/legacy mode instead of grub-efi. Thus you must disable the
whole UEFI native mode and enable CSM/legacy mode to be able to boot
grub-pc. And the multiboot won't work, you won't be able to boot a UEFI
Windows boot manager from grub-pc and vice versa.
Debian should have been installed with the installer booted in UEFI
mode, so grub-efi would have been installed.
