Cannot boot Xen: secureboot forbids loading multiboot2 module

ma flag

I've installed xen-hypervisor-4.11-amd64, now I wish to boot Xen.

I can't. When I choose corresponding entry from grub I receive following message:

Loading Xen 4.11-amd64    
error: Secure boot forbids loading module from .../grub/x86_64-efi/multiboot2.mod
Loading Linux ...
error: Secure boot forbids loading module from .../grub/x86_64-efi/multiboot2.mod
Loading initial ramdisk ...
error: Secure boot forbids loading module from .../grub/x86_64-efi/multiboot2.mod

I suspect that module is not signed, however I wish to not disable SecureBoot. What is the cause of this message, and what is the easiest way to fix this problem?

Ubuntu 21.04, Xen: 4.11, kernel: 5.11.0-34-generic

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
