It depends on what method you use. If you just need a temporary shell as root to fully uninstall system apps, try out a temporary root method like mtk-su.
If that doesn't work, you can use SnoopSnitch to check your Android security patch level and see if there’s any "Privilege Escalation" exploit that you can take advantage of.
For device-specific details I recommend you to checkout the XDA forum for your device
While I do agree that this is a double standard, I don't see any signs of it going away
