Make sure that there are no apps in the background that can drain battery. What are Your CPU and RAM usage? Also, make sure that CPU is inactive when on battery.
If You are using Linux then good luck, both power management and how switchable graphics handeled are garbage on Linux (like almost anything on that OS, at least in my experience.).

CPU and RAM usage are very low, see screenshot:
There is not app in background, I close all when I checked.
I am using Ubuntu, never hear before that have power managment issue.
I had in past 3 thinkpads, and never had this problem, all with Ubuntu.

Seem that is not nVidia: https://ibb.co/QYZLQ1J
As I remember I have two choice for graphic card when I installed Ubuntu; one proprietary (I think nVidia and another one, Intel as you mention). I choose Intel, seem. See screenshot: https://ibb.co/QYZLQ1J
Disable graphic in bios sound bad solution... I remember that without graphic card, the screen looks ugly, I have 4K.

As i said, try to google it on Ubuntu/Linux forums. Even if Linux is using only Intel graphic it doesn't mean that nVidia chip is in sleep - as i said, Linux is very poor in power management departament, especially in case of switchable graphics.
If You turn off nVidia card in BIOS everyhing will look the same if You have configured everything (drivers etc) to use Intel graphic. No matter which display You have.
But hey, this is only my suggestion so we can troubleshoot Your battery problems, do whatever You want.
