I was unable to initialize the partition using the proxmox-boot-tool

[pteromyini]

root@howie:/dev/disk/by-id# proxmox-boot-tool format /dev/nvme0n1p2 --force UUID="13564037950808554684" SIZE="536870912" FSTYPE="zfs_member" PARTTYPE="c12a7328-f81f-11d2-ba4b-00a0c93ec93b" PKNAME="nvme0n1" MOUNTPOINT="" Formatting '/dev/nvme0n1p2' as vfat.. mkfs.fat 4.2 (2021-01-31) Done. root@howie:/dev/disk/by-id# proxmox-boot-tool init /dev/nvme0n1p2 --force Re-executing '/usr/sbin/proxmox-boot-tool' in new private mount namespace..

Are you sure that you want to use /dev/nvme0n1p2 and not /dev/nvme0n1p1? It looks like you are overwriting a active ZFS vdev and it is repairing itself.
What are the outputs of zpool status and lsblk?
EDIT: The partition is 512MiB, which makes it look like an ESP.

As shown, SDG SDH nvme is the rpool hard disk.
