It is possible.
The package that is responsible for blacklisting and limiting is "com.oneplus.config"
It's in the system_ext image inside of ROM under app/OPOnlineConfig/OPOnlineConfig.apk
If you extract that APK with apktool you'll find a 110kb JSON file that has various modifiers for different apps aka it has blacklists/whitelists in it.
You can uninstall that app with adb shell by doing
pm uninstall -k --user 0 com.oneplus.config
I need to do more testing of what else is affected by removing the apk entirely but I think it'll be wise to create a Magisk module or flashable zip with modified APK to simply alter the lists and remove the list for throttling cpu frequency and leave rest to be.
