The information you seek is on the warranty legal page. The opening by any 3rd party, or installation of non-Apple parts will void the warranty and Apple will no longer support the device.
I get that it's the reality that Apple may refuse to service an iPhone with an aftermarket battery, and I believe in warning people against getting an aftermarket battery to maintain future access to Apple service. But there's very little that Apple does to warn customers about it.
It's not on the warranty page that simply having an aftermarket battery will result in loss of repair service. The US warranty info has pretty standard disclaimers. It contains a lot of "damaged caused by" disclaimers that are compliant with warranty laws.
Apple One (1) Year Limited Warranty
This Warranty does not apply:
(c) to damage caused by use with a third party component or product that does not meet the Apple Product’s specifications (Apple Product specifications are available at www.apple.com under the technical specifications for each product and also available in stores);
(e) to damage caused by operating the Apple Product outside Apple’s published guidelines;
(f) to damage caused by service (including upgrades and expansions) performed by anyone who is not a representative of Apple or an Apple Authorized Service Provider (“AASP”);
It's not in the repair terms for Apple retail stores in the US:
Apple Inc. Repair Terms & Conditions
Outside of US Apple Stores they only have the disclosure requirement:
Legal - Repair Terms and Conditions - Apple
1.11.6 Disclosure of Unauthorized Modifications. During the service ordering process, you must notify Apple of any unauthorized modifications, or any repairs or replacements not performed by Apple or an Apple Authorized Service Provider (“AASP”), that have been made to your product. Apple will not be responsible for any damage to the product that occurs during the repair process that is a result of any unauthorized modifications or repairs or replacements not performed by Apple or an AASP. If damage results, Apple will seek your authorization for any additional costs for completing service even if the product is covered by warranty or an AppleCare service plan. If you decline authorization, Apple may return your product unrepaired in the damaged condition without any responsibility.
The US AppleCare+ terms are the only place I've seen it mentioned officially by Apple:
Legal - AppleCare+ - Apple
3. What is not Covered?
3.1 Hardware Services and ADH Services
Apple will not provide Hardware Services or ADH [accidentally damaged hardware] Services in the following circumstances:
(g) to repair any damage to Covered Equipment (regardless of the cause) if the Covered Equipment has been opened, serviced, modified, or altered by anyone other than Apple or an authorized representative of Apple;
