Well you can try using a private dns for that purpose or try blocking’s the apple revoke system
Step 1
Follow the steps to create your own DNS. [Remove any other DNS you have (adblock, etc.)]
When creating your DNS, you have multiple services to choose from (or you can host your own server). I’d recommend:
NextDNS
Create an account
Go to “Denylist”
Add the following links to the denylist:
DenyList Links
Add this link to the allowlist (Only if you want to use Feather)
app.localhost.direct
Add this link to the allowlist (If you're not able to use ChatGPT)
register.appattest.apple.com
Step 2
Once your denylist is set up, install the DNS profile by going to the "Setup" tab and downloading the config profile.
Then, enable the DNS and ensure it is turned on in "VPN & Device Management," found under "General" in settings.
If you have another DNS, make sure to disable it, and turn off any VPN.
Step 3 (Optional: To add AdBlock)
Go to the "Privacy" tab and add a blocklist.
Add any ad blocker you prefer.
