A.T. Robertson Commentary Romans 10:3

"For being ignorant of God`s righteousness, and seeking to establish their own, they did not subject themselves to the righteousness of God." — Romans 10:3 (ASV)

Being ignorant of God's righteousness (αγνοουντες την του θεου δικαιοσυνην). A blunt thing to say, but true as Paul has shown in 2:1-3:20. They did not understand the Godkind of righteousness by faith (1:17). They misconceived it (2:4).

They did not subject themselves (ουχ υπεταγησαν). Second aorist passive indicative of υποτασσω, common Koine verb, to put oneself under orders, to obey, here the passive in sense of the middle (James 4:7) like απεκριθην, I answered.
