Yes, it is possible. But if it can help you troubleshoot - why not ?!
The original manual, in my opinion, is not worth the money!

I think - the electronics itself will limit the battery charge, if it has the proper software, without errors.

I asked about a program that can show the capacity of a high voltage battery.

Car Scanner.

Found on the internet: "Chevrolet Bolt EV 2017 2018 2019 Factory Workshop Service Repair Manual on CD" https://www.ebay.com/itm/Chevrolet-Bolt-EV-2017-2018-2019-Factory-Workshop-Service-Repair-Manual-on-CD/224147146422?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D225074%26meid...

Not quite clear. From the information given, for a 2017 car - 57 kWh

What is the available capacity of the high voltage battery? Do cars of different years (2016-2020)?

Where can I download the 2017 Chevrolet Bolt service manual?

What program can measure SOH (or kWh) high-voltage battery?
