Did not manage to do a first test with all modules unloaded (many are in use), so made a simple script that runs rmmod on all loaded modules, logs the result and then shuts down the laptop. Running unmodified 5.15.0-33-generic Ubuntu kernel at the moment. To be able to use "rmmod -f" I would have to rebuild the kernel with CONFIG_MODULE_FORCE_UNLOAD=Y, but maybe the modules that can be unloaded now will already help find the culprit. Battery drain is usually around 2% per day, so will report back in a couple of days.
