I am not completely sure what you mean. If you mean the capture side, I am not convinced that is possible, and I sadly cannot help you. If you, however, mean programming the target-side of the ChipWhisperer Lite capture board (meaning the hardware which will actually execute encryption/decryption algorithms etc.). You can do this with the programmers available within the python library.
from chipwhisperer.capture.api.programmers import STM32FProgrammer
# Initiate a new STM32F Program
# STM32 being the ARM microcontroller that the CW Lite ARM is using
# If you are using the AVR version, you should probably use
program = STM32FProgrammer
This is an adapted excerpt from this file. Resources on this are rather scarce on the official docs, so I’m just going to point to something I wrote myself. Introduction to Power Analysis - Capturing Traces.
Hope that helps!
