Here is another idea to split your “VPN“ and “non VPN“ activity. - Use a virtual machine with a system wide VPN.
Outside the VM do all the activity that is linked to your identity, like banking. Protect yourself from nosy third parties just with ad blockers and DNS filters there.
Inside the VM where you have system wide VPN, do everything that should not be linked to your identity, like writing pots in some unsavory forum, watching po… politics, pi… piloting copyrighted content and meeting up with your ha … harmless friends.
Use the Tor Browser outside or even better inside your VM to really stay anonymous when you resurch sensitive topics like illness, debt and other issues you would be “downgraded“ for.
