YEs brother.
You may make du'a in your own language in your sujoud as well as before making the tasleem knowing that you have already read all the supplication of the prayer in Arabic like the Subhaana rabbiyal a'laa 3 times and then make du'a in your own language - read all the At-tahiyyaat and then make in your own language.
Shaykh al-Islam Ibn Taymiyah said:
It is permissible to make du’aa’ in Arabic and in languages other than Arabic. Allaah knows the intention of the supplicant and what he wants, no matter what language he speaks, because He hears all the voices in all different languages, asking for all kinds of needs.
Majmoo’ al-Fataawa, 22/488-489.
Allah knows best.
