Yes. Firewalls.
With an iPhone, however, you are screwed. Apple won’t let you do what you are looking for.
You can enforce an always-on VPN (for at least ipsec) via an MDM profile. This kind of features isn’t found in the casual user setup options, but there’s plenty of knobs to tune in the enterprise profile configurator.
And yes, you can easily install that profile on your phone after.
Except, apple is bypassing VPN for their own tracking:

That’s really shitty given the expectation set when using a VPN
Yes!

VPN would still work for iPhone I imagine. Small whitelist of DNS would do 90%+ of the job.
Apple bypasses VPNs for certain system services, or at least has in the past
Also falls back to hardcoded IPs when DNS fails
True, somewhat… but on the iPhone, many functions that seem like basic things are tied to Apple’s services and cannot easily replaced by selfhosted services. This phone would not work properly anymore.
