ICS (Internet Connection Sharing), VPN and split tunneling

With WFH situation, i need some guidance. We have some devices that required our VPN connectivity. So our solution is to use ICS (Internet Connection Sharing) from the VPN connection from a Windows PC with 2 NIC. It works well as it is. However, I am wondering if there is a way to force the devices to connect particular URL with the Internet interface and not the VPN. I tried adding to ipv4 route table but didn't work.

Network Destination Netmask Gateway Interface Metric 4.4.4.4(example) 255.255.255.255 192.168.1.1 192.168.1.148 51

VPN interface (shared to ICS interface) - 10.10.0.10 Internet interface - 192.168.1.148 ICS interface - 192.168.137.1 Device (connected to ICS interface) - 192.168.137.192
