I have an isolated network and with that network i have created a vm and in that vm i have attached anotehr isolated network so that it could reach both the isolated networks but if i see inside the vm there is only one NIC is showing which is set default from the network panel of the vm but is there any way to activate both the NICs at the same time so that one vm can reach multiple isolated network

ubuntu@ssh-gateway-vm:~$ ip a

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    inet 127.0.0.1/8 scope host lo

       valid_lft forever preferred_lft forever

    inet6 ::1/128 scope host noprefixroute

       valid_lft forever preferred_lft forever

2: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000

    link/ether 02:03:00:d8:00:4b brd ff:ff:ff:ff:ff:ff

    altname enp0s3

    inet 10.2.20.216/16 metric 100 brd 10.2.255.255 scope global ens3

       valid_lft forever preferred_lft forever

    inet6 fe80::3:ff:fed8:4b/64 scope link

       valid_lft forever preferred_lft forever

3: ens4: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000

    link/ether 02:03:00:d5:04:1d brd ff:ff:ff:ff:ff:ff

    altname enp0s4

My goal is that i want a vm which can reach other isolated networks
