Seems like you want help, but you want it on your terms. For me, I despite not using Docker, I read this post initially, got to the point above and completely lost interest, as it came across as I want what I want without providing the requested information as it does not suit my purposes. You may disagree, but this is how I, and possibly others would interpret this sort of response.
Regarding your newer issues/comments, if I came here and saw this topic and had previously dismissed it as not applicable, it is not clear from the subject that you have additional issues like your Apple watch, not getting a hostname from DHCP, and such. If it were me, I would have created separate topic specific posts, or if I already had a post appropriate a topic used that. While this may not suit your needs, you want help, so make it easier for those you are hoping can help you. That is an approach that works for me.
Regarding the Apple watch, my family members who have WiFi based Apple watches have no issues using Pi-hole. Perhaps you are using an ad block list or have a block entry that is involved. No real idea, but that probably would get more action in this post of yours (Apple Watch issues again)
Be well.
