Hi,
The link is crated in
/etc/systemd/nvpower.sh
For further checking you may check why it does not link to /etc/nvpmodel/nvpmodel_p3767_0003_super.conf
p3767 0003 is Orin Nano module without SD card slot. p3767 0005 Orin Nano module with SD card slot. Both modules use either nvpmodel_p3767_0003_super.conf or nvpmodel_p3767_0003.conf.
