According to your situation, you can only apply for assistant social workers now. You can apply for assistant social workers if you have obtained a bachelor's degree or above in other majors and have been engaged in social work for 2 years. The application conditions for social workers are relatively strict. Because you are not a social worker, you can only refer to this one: "After obtaining a high school or technical secondary school education and a professional level certificate for assistant social workers, you have been engaged in social work for 6 years."

I don't know if I'm right. Social workers who graduated from undergraduate courses can directly apply for assistant social workers. You can ask the local vocational examination institution for details.
