Create ifcfg-enp0s3 and ifcfg-enp0s8 files manually. The samples are /usr/share/doc/initscripts-*/examples/networking/. However if you use static IP address, essential items are here:

TYPE=Ethernet
BOOTPROTO=none
NAME=enp0s3
DEVICE=enp0s3
ONBOOT=yes
IPADDR=192.168.100.3
NETMASK=255.255.255.0

Or if you prefer to use DHCP :

TYPE=Ethernet
BOOTPROTO=dhcp
NAME=enp0s3
DEVICE=enp0s3
ONBOOT=yes
