I think you need policy routing: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_networking/configuring-policy-based-routing-to-define-alternative-routes_configuring-and-managing-networking https://doc.lagout.org/network/inetdoc/Policy_Routing_in_Linux_ENG.pdf Although it may be tempting to use some sort of round-robin, it would be safer to have specific rules based on the destination, so for example you send all web traffic to one ISP and add exceptions to route specific traffic to the second ISP (e.g. streaming platforms), with each rule having a "backup route" to the other ISP.
