If you feel adventurous (and your router is supported): https://openwrt.org/
However, many routers support DHCP reservations even with stock firmware.
An alternative is to set up a a small SBC with ethernet as a network server
and run DHCP server (and possibly other services like local DNS) on it.
Such board can be also used as a gateway and firewall for "smart" and IoT
devices, you can use it to set up multiple wireless networks (using one
wireless adapter) to isolate devices from your home network, or for guests.
It can be very helpful if you would like to curb traffic from "smart" TVs
and other devices sending out reports about your activities. This, however,
requires quite a bit of knowledge about network configuration.

Still, the easiest solution to static DHCP allocation is to find a router
which has it implemented.
