Bootable disks replacement and ZFS on Proxmox 6.1-8

Hello! I need help.
Proxmox 6.1-8
It was installed on pool of 4 HDD, and two of them contains boot and efi partitions.
I need to replace all 4, they are too old and unreliable.
One of this disks is already faulted, I've detached it (zpool detach /dev/disk-by-id/disk_id and then physically), and plug in a new one, but didn't set it up yet.
What are the steps to safely replace those disks without making the system unbootable?
I found this topic,
with advise to follow wiki instructions,
but it mentions proxmox-boot-tool wich is not installed on my system (probably there is no such tool in Proxmox 6.1-8) and I can't find it with apt. Is it possible to get this tool on my version 6.1-8?
Or is there any kind of instructions without proxmox-boot-tool?

New HDD isn't a part of pool yet and have no partitions at all.
Other 3 has a layouts:

Should all 4 of them have "bios boot" and EFI partitions and how to add those on new drives?

I'll be glad to provide any additional information.
