I personally used adguard & adaway to block ads on my phone, if i want to block ads on another device I just tethered phoje Wi-Fi to target device.
Even nowadays i still used my phone as portable router to block ads & tracker when i used my laptop

Well technically you can block ads as long as your phone or other device that works as hotspot/Wi-Fi tethering has adblocker that runs on root level since car need network to connect it.
On root level adblocker nothing can escape even the sneakiest ads will got blocked (as long as your adblocker has feature like uBlock origin filters & you have matching filters)
