Load graphic module on systemd-boot?

Is there anyway to load the graphics module (nouveau/amdgpu) on systemd-boot?
I have two laptops (one with an nvidia the other with an amd) that only output to the external displays after the graphics modules are loaded. This means that the bootloader is not visible on the external displays, which is not great when using them in clamshell mode.

Any suggestions?

The kernel modules are, well, kernel modules. They won’t do anything in the bootloader, before the kernel is loaded. You’ll need to look at some uefi settings.

No uefi settings on these, unfortunately.
What about having an efi image with a light Linux kernel (with the graphic module) that would be loaded early instead of systems-boot. That image could then display the generations list and boot one of them. Is something like that possible?
