if the system is indeed booted with grub (legacy BIOS) instead of
systemd-boot (UEFI) - then you just need to run
`proxmox-boot-tool refresh` (as the warning suggests)

if the system is booted with systemd-boot - then you need to configure the
kernel commandline parameters in /etc/kernel/cmdline (instead of
/etc/default/grub) (see [0])- the bootloader screen itself will be on the
serial terminal, if it's configured in the UEFI/BIOS settings on the
machine itself.

I hope this helps!
