You will still still to disable conntrack from PREROUTING for stateless dnat,
so this would be:
nft add rule raw PREROUTING ip saddr { 1.1.1.1, 1.1.1.2} notrack
The rule above disables conntrack for traffic coming from 1.1.1.1 and 1.1.1.2,
then:
nft add rule mangle POSTROUTING ip saddr set ip saddr map { 1.1.1.1 : 2.2.2.2,
1.1.1.2 : 2.2.2.3 }
This rule performs the stateless snat.
I can place these examples in the wiki if you like.</pre>
