Is /efi/ubuntu/grubx64.efi on your EFI System Partition definitely the
Canonical-signed image from grub-efi-amd64-signed?

Which version of Ubuntu's grub are you booting via pxe?

If you re-enable SecureBoot and configure this system to boot directly from
local disk instead of booting pxe first and chainloading, does it boot
successfully?
