I confirmed that there is a problem with creating and editing boot menu entries that that point to a disk other than the disk which guefi in running from. All the other guefi functions seem to work without problems.
There is nothing in the UEFI specification that limits the number of ESP partition that can be on a system, so guefi should be able to detect multiple partitions across all the internal storage devices and be able to create and edit entries that point to the various ESP partitions.
I'm no expert on writing code, but you can cull out the ESP partitions on a system using fdisk. Here's an example using an overly exaggerate number of esp partitions :
sudo fdisk -l -o DEVICE,TYPE | grep "EFI System"
/dev/sdb1 EFI System
/dev/sdb4 EFI System
/dev/sda5 EFI System
/dev/sda6 EFI System
/dev/sda8 EFI System

I guess after soon 3 years, it is safe to close that issue
from guefi.

I'm reopening, as I actually want this fixed. I completely forgot about it. I'll get to it, soon I hope.

I tried testing this. I created EFI partitions on two drives. But efibootmgr only shows one
PciRoot(0x0)/Pci(0x1,0x1)/Ata(0,1,0)
entry for the other drive, not the actual boot entries that are in the EFI partition of the second drive. This is with efibootmgr version 17. Specifying -d sdb doesn't change anything at all. Do you still get all boot entries, irrespective on which partition they are listed with efibootmgr?

Just installed 15 beta on my tower computer that has three hard drives
and one nvme drive. Two of the three hard drives and the NVMe drive
have EFI partitions. Here's the output of efibootmgr from the Salix 15
install;

PciRoot(0x0)/Pci(0x14,0x0)/USB(7,0)/USB(2,0)/CDROM(1,0x5b0,0x2d00)..BO
Boot item 0000 is on sda1 efi partition. Boot items, 0001, 0002, 0003
are on the nvme0n1p1 efi partition and Boot items 0004 and 000B are on
the sdc1 efi partition.
One thing I did note was that efibootmfgr (version 17) included in Salix
15 defaults to the verbose output. Mint 19 also uses version 17 and its
default output is the simple boot listing like what was in salix 14.2.

Specifying |-d sdb| doesn't change anything at all. Do you still get
