You can use this command:

 ip route add default via $ip_address dev $interface onlink

but I'm not sure it's supported in d-i -- most likely not.

I think your setup is not right.  Yes it works, and linux allows
you to have more weird setups too -- like pretending that ethernet
is a pointopoint interface like ppp -- by using exactly the same
"device route" mechanism too, but it is not how networks are
designed to function.

It is something like complaining that in order to overclock your
CPU too much you have to open your PC case and move some jumper
on a motherboard - yes the CPU works after that, yes it has enough
protection features to not melt down due to overheating, but it
is not its normal mode of operation.  Maybe not a fair comparison
but it shows an idea.
