How to setup two IP addresses on Ubuntu 18, in the same NIC?

Hi folk,

I would like to learn how to setup my network card with two IP addresses
In the Ubuntu 18.04 using netplan, I cannot use alias to the same network interface.
I need to setup a nic with two IP addresses, and each IP needs a distinct default gateway

In the Ubuntu 16.04 I can to configure as bellow:

auto ens160
iface ens160 inet static
address 192.168.98.248
netmask 255.255.255.0
gateway 192.168.98.5
dns-nameserver 192.168.98.247 8.8.4.4 208.67.222.222
dns-domain xyz.local

auto ens160:0
iface ens160:0 inet static
address 172.16.10.2
netmask 255.255.0.0
gateway 172.16.10.1

How can I do it in the Ubuntu 18.04 using netplan?
Could you please help me?

Thanks,
