'how to configure static routes via specific interface in netplan

I need to configure static routes via interface rather than gatewayIP, is it possible? say we have to use "via: IP" in netplan like:

   routes:
   - to: 10.100.0.0/16
     via: 192.168.200.1
     metric: 100

but in ip route cli command, it doesn't have to specify via gateway IP, like:

sudo ip route add 10.100.0.0/16 dev enp0s25

The question is , how to do it in netplan?
