For TX2 there appears to have been support for external triggering of cameras (see thread below), but it was removed from the BSP at some point and then “promised back in the future” like in this thread:
There are tons of forum threads on this request with people wanting it but being told that it is not supported for this and that Jetson Model and that only a streaming stream is supported - apparently because you have hardcoded MIPI timeouts and thus not allowing single capture - despite that some appears to have gotten around the hardcoded timeouts somehow
What I’m talking about here is having a CSI camera (with global shutter) that is being manually triggered to capture frames - instead of a continuous stream - the trigger is via a dedicated trigger input on said camera and every time it receives a trigger it will output a MIPI CSI frame.
The trigger could be a push button where someone is pressing once a day, once a minute or faster obviously…
The trigger could also be a sensor on a machine conveyer taking a picture every time something passes… which could be at 25fps or 1fps or something else entirely…
For raspberry pi there is such a mode see here for example

My question is - is it possible to get “snapshot” mode to work on TX2 or any other Jetson ?
