Hi,

yes it can be done using sdwan and if sdwan is not setup and policy route can be used

Refer:-

If you meant "from all internal network", any routers can do that without SD-WAN or policy-routes, just setting specific routes for those destinations to each ISP interface.
If some specific internal sources need to go one ISP and the others need to go the other ISP for the same destinations, you have to use policy routing or SD-WAN.
