Assuming 192.x.x.0 is on ether1 and 10.x.x.0 is on ether2, you could just drop the “wrong” addresses in the interfaces’ output firewall chain, like

/ip firewall rule output add src-address=192.x.x.0/24 out-interface=ether2 action=drop
/ip firewall rule output add src-address=10.x.x.0/24 out-interface=ether1 action=drop
