J101-v2 carrier board from Seeed - Unusable 40pin header

I am interested to know if someone of you by any chance has the J101-v2 carrier board for jetson nano and was able to configure the 40pin header (spi interface) ?

I installed the dt-overlays according to https://github.com/Seeed-Studio/seeed-linux-dtoverlays to be able to use the SPI interface but when I want to manually configure the 40pin header I receive this error:

| |
| |
| Failed to get pin number for node |
| /fragment@10/__overlay__/header-40pin-spi0-pinmux/pin18/! |
| |
| Press any key to terminate

I addressed my issue to their support and I received this reply which is very ambiguous to me:

This device can only be used with the official nvidia jetson nano dev kit.

Output of /opt/nvidia/jetson-io/config-by-hardware.py -l is:
