I run a dual-boot setup on my main workstation for testing purposes.
My main driver is a fully updated Manjaro Linux.
I boot said Manjaro installation using GRUB installed to the NVMe0-drive's EFI-partition.
Proxmox is installed onto NVMe1.

When running "update-grub" the bootloaders of all other operating systems that have been installed on NVMe1 were detected by OS-prober and added to Manjaro's GRUB-boot-menu. (Windows 10 and 11, Ubuntu, among others)

Proxmox VE is not detected by OS-prober on Manjaro, thus not added to the boot menu, forcing me to change uEFI-settings everytime I want to boot into my lab environment. Which is annoying.

Is there any way to make PVE's bootloader visible to OS-prober of another linux installation?
