Is it possible to flash Nvidia Xavier NX (mounted on A205 carrier board) on an SD card?

Hi all,
after looking online for info and clarifications I still cannot find an answer to my question:
is it possible to flash Nvidia Xavier NX (mounted on A205 carrier board) on an SD card ?
It seems quite possible to do this on external USB or SSD devices but I cannot figure out how to use an SD card istead.
Thanks in advance for the support !

Rather ask in the Xavier NX forum:
