I'd start looking within the community forums centered around the OS your are using
Also, if you can install Docker on your OS, you may be able to run Pi-hole from a Docker container, e.g. by adapting guides like this beginner-friendly one focussing on Portainer, Docker and Pi-hole.
If you'd decide to have Pi-hole as DNS and DHCP server (completely optional), be sure to consult Pi-hole's documentation on dockered DHCP for a few caveats.
I had no joy and that's why I came to you I went the Docker way, it worked immediately! I have not delegated DHCP to pi-hole because the platform is sort of live with DHCP already running. This will be the last step.
I have built a block list and debugging FP (i.e. Facebook is KO).
