Are there any APIs available in JetPack to put the device in sleep mode (for example use DL accelerator only when it is required and put it in the low power sleep mode when it is not required to reduce the power consumption of the overall device power usage? and any documentation to explain this?
You can control power mode by nvpmodel. Please check following document first:
You can also turn off the display to save some power:
$ sudo systemctl stop gdm $ sudo loginctl terminate-seat seat0
