Sorry, I don't understand what you mean here.  Do you mean you do have the
grub-efi-amd64 package installed, or you don't have it installed?

The Windows bootloader will not boot anything not signed by the Microsoft
key, even if Secure Boot is disabled in the firmware.  If your Ubuntu
install has not yet been set up for Secure Boot, you will need to disable
Secure Boot, and manually choose Ubuntu from a firmware boot menu.

If you installed grub-efi-amd64, did you also try again to install
shim-signed after that?  This should be the last step to enable Secure Boot
on your Ubuntu install.
