This has no equivalent.  The rule above matches when 'call-iptables' sysctl
is enabled and the packet did not enter via a bridge interface.
So, its only false when it did enter via a bridge interface.

In case the sysctl is off, the rule always matches and can be omitted.

nftables currently assumes that call-iptables is off, and that
bridges have their own filter rules in the netdev and/or
bridge families.

inet/ip/ip6 are assumed to only see packets that are routed by the ip
stack.

fib saddr type != local
