Hello Louis, I can see this CONFIG_NF_TABLES got enabled in 5.4 KVM kernel now.
$ grep CONFIG_NF_TABLES /boot/config-5.4.0-1026-kvm CONFIG_NF_TABLES=m CONFIG_NF_TABLES_SET=m CONFIG_NF_TABLES_INET=y CONFIG_NF_TABLES_NETDEV=y CONFIG_NF_TABLES_IPV4=y CONFIG_NF_TABLES_ARP=y CONFIG_NF_TABLES_IPV6=y CONFIG_NF_TABLES_BRIDGE=m Therefore I am going to close this bug, please feel free to open a new one if this is still not working for you.
