Seperate home is a must imho. Fedora had kickstart but alas a little old. This may help. https://discussion.fedoraproject.org/t/here-is-how-to-easily-create-a-bootable-clone-of-your-fedora-system-disk/111308

Glad to help

U can but alas only ipv4. I disabled ipv6 in the router and everything is fine. Ipv6 if i read correctly is hardcoded into android and i cannot change my routers dns

Dhcp.

To clarify new android phone bypasses pihole with ipv6 isp box cant configure anything. Would this work?

Are you able yo host alongside freenas or on top of?
