If it were me I'd compile a Go DHCP daemon because they're fully static. All you'd theoretically need is the compiled binary and a config file. Copy (scp) those to the AP and run it. No idea if it would really work, but it seems like it could. Something like this: https://github.com/coredhcp/coredhcp - README even provides example compile and run commands and a simple 8 line config file. If you've never setup Go it might take you a bit, but it's gotten a lot easier in recent years.
