I appreciate that this is frustrating, but you have two choices whenever deploying any form of solution- pay for it or learn how to do it yourself. all your questions are answerable by googling generally and searching this forum specifically. If you are unable/unwilling to research and give up, I doubt anyone here will be offended.

IF you want to boot from a hardware raid volume, you have to specify it as the booting lun in your controller bios. you can start here: http://h10032.www1.hp.com/ctg/Manual/c02289065.pdf

IF you want to boom from a zfs lun and are getting stuck in grub, you may wish to consult the Proxmox documentation, which is pretty good- have a look here: https://pve.proxmox.com/wiki/ZFS:_Tips_and_Tricks#Grub_boot_ZFS_problem

I appreciate your interesting in my problem. I've found that using UEFI + ZFS i can boot using the install usb in rescue mode. So i thought... is it possible to install grub on a USB stick, boot from it telling to boot the ZFS pool?

sure, you can do custom boot configurations however you want - booting from a different device than where your rpool is located is entirely possible if you know what you are doing.
