I am choosing the HDD in the caddy, from the bios boot menu.

The internal HDD has windows 10 on it. I do not want to loose that, in
case i need to get back to windows, for video conferencing apps, etc
that are not supported yet on NetBSD.

I did not try putting a different OS on the HDD in the caddy.

What i tried though is this. I have removed the internal HDD (that
contains Win10) from the system and put the NetBSD disk in its place.
This booted NetBSD.

I also put the NetBSD disk into the caddy, but no internal HDD, NetBSD
booted without problems.

What i would like is to keep the internal disk, but have the system
boot from the caddy.

I am using UEFI (no secure boot at the moment). The NetBSD disk also
has the UEFI partition (128MB) that contains the bootx64.efi, and
another *.efi file.
The NetBSD disk has the root partition, the swap, partitions as well.
