Migrating PVE server from grub (legacy BIOS mode) to UEFI

i have a proxmox server installed years ago and upgraded from 4.x up to 7.3 currently. the server was installed in legacy bios mode.
firmware upgrades are not supported in this mode, so i would like to migrate to uefi. it is a single node installation (home server) with a couple of VMs on it. Additionally there are lots of scripts docker-containers on the host itself.

is there an inplace switch to UEFI possible?

kind regards,
ah cool. first question after a quick look: i am running on ext4. would that work, too (clearly i wouldn't perform the zfs steps)?
