Yes. Any basic OBD tool that connects to your phone via WiFi combined with a decent app (I use CarScanner) will show you some of this information. When I watched stats on my 2020 5.7 w/ eTorque (prior to trading for an EcoD), I noticed the pack voltage hovered around 44V and typically stayed around 60% charged, going as low as about 50%, and as high as about 85%. Regen ONLY occurred on my truck when I actually applied some amount of force (even slight) to the brake pedal - coasting did NOT ever regen to the battery. Regen power is about 8.8 kW (44V times 200 amps at peak). After regen and upon resuming accleration, the electric motor would apply about 2.2 kW of assist power (44V * 50A~) until the battery hit its programmed idle capacity of around 60%. Charge and discharge does not take long since the pack is so small (430 wH), and the power input/output is substantial in comparison. You can also see that eTorque does indeed play a role in shift behavior based on current input/output during shifts - it will slow down the engine for upshifting (regen in the process) and speed up the engine for downshifting (uses stored power).
This is the tool I have - anything similar should work.
