I do change /etc/default/grub and get new entry in UEFI.
GRUB_DISTRIBUTOR=kubuntu
But it always uses /EFI/ubuntu/grub.cfg to boot not /EFI/kubuntu/grub.cfg. But a different entry in UEFI.
Or you can create an entry like shown in Bug above with grub-install --bootloader-id=myid or just in UEFI with efibootmgr and different description.Entry in UEFI uses GUID/partUUID to know which ESP to boot from. 
Most systems only allow one active ESP per device, but once configured, you may be able to use any FAT32 partition with .efi boot files.

If in different ESP, then any of the options to create a different id
should work, but you may need /EFI/ubuntu folder in ESP as well.

Title:
  When installing grub to multiple EFI partitions they all have the same
  label in the EFI vars

Status in grub2 package in Ubuntu:
  New

Bug description:
  I have been trying out the new facility to install grub to multiple
  efi partitions.  Both of the efi entries shown in efibootmgr have the
  same label and these are all that is shown in the boot selection menu
  on my systems making it impossible to distinguish between them.

  Each entry should be given a different label to enable choosing the
  entry required.

  I am using grub2 (2.04-1ubuntu26) on a Focal system.
