How I do it:
1-don't have NetworkManager installed
2-have systemd-networkd installed
3-don't have systemd-resolved or resolvconf installed
4-configure systemd-networkd with static IP
5-configure /etc/hostname & /etc/resolv.conf manually
6-configure host in /etc/hosts
My PCs are almost exclusively desktops, and none ever leave the building.
