I don't quite understand your question, but "Safari includes tracking and fingerprinting protections that help prevent websites from tracking your device."

Enabling Advanced Tracking and Fingerprinting Protection on your iPhone is designed to enhance user privacy by limiting tracking methods, including fingerprinting techniques.
WebKit feature flag for Enable Canvas Fingerprinting is enabled by default, Does this flag permit certain tracking methods that the Advanced Tracking and Fingerprinting Protection settings aim to block??. Essentially having both features active would undermine the privacy intentions behind the Advanced Tracking and Fingerprinting Protection.??
I understand your concern. The "Enable Canvas fingerprinting-related quirk" Webkit feature flag is understandably vague and I do not know just which quirk it addresses. However, it and Advanced Fingerprinting Protection do not contradict one another or otherwise cancel their combined effects.
You can read some limited information about AFP here, but thwarting personal information-harvesting and intrusive tracking is a constantly evolving challenge as website developers and SEOs implement increasingly devious ways to circumvent it:

I surmise the ability to enable or disable the "Canvas fingerprinting-related quirk" is present since its setting (either enabled or disabled) can result in unexpected website behavior. It's not practicable to anticipate exactly how that misbehavior could manifest.
