bootcode update after zpool upgrade

I did "zpool upgrade tank0" on one of our machines with FreeBSD 12.2-p13 
amd64 and then got this message:

# zpool upgrade tank0
This system supports ZFS pool feature flags.

Enabled the following features on 'tank0':
   large_dnode
   spacemap_v2
   allocation_classes

If you boot from pool 'tank0', don't forget to update boot code.
Assuming you use GPT partitioning and da0 is your boot disk
the following command will do it:

         gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 da0



I am not sure what I should update. This machine is EFI boot only (this 
is the only one EFI machine we have).

# gpart show

           40      409600     1  efi  (200M)

Should I run:
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 2 nvd0
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 2 nvd1

Or should I update EFI partitions? (if so, then how?)

This machine is very problematic with booting and mounting NVME disks. 
They are not visible until I disabled PCI hot plug with 
hw.pci.enable_pcie_hp="0" in /boot/loader.conf

This is production machine so I would really like to do it right and not 
make it unbootable.

Kind regards
