anarchosax If there's only that one disk, with those 3 partitions you've shown, then how come the find command didn't show any of the rEFInd files which're sitting on the same partition (judging from the GUIDs as shown)?
But, that's an aside. What you should do now is go into the BIOS, and see if you can add an entry for NetBSD.
(Most BIOSes automatically make entries for any /EFI/boot/*.efi files--standard locations on ESP-type partitions--don't know why yours isn't.)
Or, this command may work (careful!):
efibootmgr -c -L NetBSD -d /dev/sda -p 1 -l '\EFI\BOOT\BOOTX64.EFI'
(assuming, here, that the disk is /dev/sda)
You can't do this (yet) from NetBSD 10.x.
You should also clean up any unused entries:
efibootmgr -B -b 000E
efibootmgr -B -b 000F
etc. (whichever bootnum is leftover crud).
