You could potentially disable its DHCP server and put another one on
the network which you can control.  I realize we're straying from
out-of-the-box, but your network design isn't really out-of-the-box
either and that is part of the problem.  The consumer-grade stuff is
really designed to be used as the gateway + access point, etc.

OpenWRT probably can do the job, but I suspect the LUCI web-based
config page isn't up to it.

The docs seem to be here: https://wiki.openwrt.org/doc/uci/dhcp

You can probably edit the text-based config file to have it set the
default gateway, or set it per-host.

Personally I'd be just as inclined to just run dhcpd on something.
The normal dhcpd configuration file seems a bit more friendly for this
sort of thing.  I run a dhcp server on a pi so that I can tweak stuff
like this without having to stick static network configs on lots of
hosts/etc.  Running dhcpd on most distros isn't all that hard - right
now I'm just running it on Raspbian but I've also done it on Gentoo.

But, tweaking all the hosts is certainly an option.
