Do I send SAT 2 score to UC's if.....

Under the SAT subject tests score section in the UC app, I entered the my SAT 2 Japanese score.

However, I used my ACT test scores and do not want to send any of my SAT scores.

My question is, do I need to send my SAT 2 official score report, or is it okay to just self report since SAT 2 is not required? I’m asking this since UC is not score choice college.
If I do need to send, can I just score choice only my SAT 2 test?
